If the **acid is monoprotic**, the **molar mass** was calculated to be 58.94 g/mol, 117.9 g/mol if diprotic, and 176.8 g/mol if triprotic. The molarity of the NaOH solution was calculated to be 1.003M, the average molarity of the first two trials._{Oct 5, 2017}

How do you find the molar mass of a Diprotic acid?, Since the **acid** is **diprotic**, you had half that number (0.00580 moles) for the **acid**. That’s just the amount of **acid** in 25 mL. The amount in the original 200 mL solution is 0.0464 moles. This means the **molar mass** will be 4.50 g / 0.0464 moles, or 97.0 g/mol.

Furthermore, How do you find the molarity of an unknown acid in a titration?, If the titrant and analyte have a 1:1 mole ratio, the **formula** is **molarity** (M) of the **acid** x volume (V) of the **acid** = **molarity** (M) of the base x volume (V) of the base. (**Molarity** is the concentration of a solution expressed as the number of moles of solute per litre of solution.)

Finally, What is the molar mass of a Diprotic acid?, If the **acid** is monoprotic, the **molar mass** was calculated to be 58.94 g/mol, 117.9 g/mol if **diprotic**, and 176.8 g/mol if triprotic.

## Frequently Asked Question:

### How do you calculate the molar mass of an acid?

025 gram, but you want to **find** the **molar mass**, or the **mass** for one mole. So, set up another proportion: x/. 025 g = 1 mol/. 00315 mol, and you **find** that x = 7.94 grams, which is the **molar mass** of the **acid**.

### How do you find the KA of a Diprotic acid?

for the **acid**. If you **know** the concentration of the of the **acid**, say it is 0.0027M and the Ka1 is 5.0×10−7 . Then you can set up your equation as follows; H2X –> H+1 + HX−1 with Ka1 = 5.0×10−7 Using the formula: **Ka**=(products) / (reactants):

### How can you tell if an acid is Diprotic?

For a **diprotic acid**, you can find the first **acid** dissociation constant the same way as for a monoprotic **acid**. The second **acid** dissociation constant is the point halfway between the first equivalence point and the second equivalence point.

### What is a Diprotic acid?

A **diprotic acid** is an **acid** that yields two H^{+} ions per **acid** molecule. Examples of **diprotic acids** are sulfuric **acid**, H_{2}SO_{4}, and carbonic **acid**, H_{2}CO_{3}.

### How do you calculate the molar mass of a solution?

Step 1: List the known quantities and plan the problem. to **calculate** the molality of the **solution**. Then use the molality **equation to calculate** the moles of solute. Then divide the grams of solute by the moles to **determine** the **molar mass**.

### How do you find the molar mass of sulfuric acid?

98.079 g/mol

**Sulfuric acid** / **Molar mass**

Go to periodic table and determine the atomic mass average (atomic weight) of each element. Multiply each atomic mass by the number of atoms in the formula. Add up the results of step three: 2.015+32.066+63.998 = **98.079** = molar mass of sulfuric acid.

### How do you find the concentration of an unknown acid?

An **acid**-base titration is used to **determine** the **unknown concentration** of an **acid** or base by neutralizing it with an **acid** or base of known **concentration**. Using the stoichiometry of the reaction, the **unknown concentration** can be **determined**.

### How do you find the concentration of an unknown solution?

Divide the mass of the solute by the total volume of the **solution**. Write out the **equation** C = m/V, where m is the mass of the solute and V is the total volume of the **solution**. Plug in the values you found for the mass and volume, and divide them to **find the concentration** of your **solution**.

### How do you find the concentration of an acid?

**Step 3: Calculate the concentration of hydrochloric acid in mol/dm 3**

- Concentration in mol/dm 3 =
- Concentration in mol/dm 3 =
- = 0.125 mol/dm 3
- Relative formula mass of HCl = 1 + 35.5 = 36.5.
- Mass = relative formula mass × amount.
- Mass of HCl = 36.5 × 0.125.
- = 4.56 g.
- So concentration = 4.56 g/dm 3

### How do you identify an unknown acid?

The titration curve of an **unknown** weak **acid** with a strong base will be measured using a pH meter. From the titration curve, the equivalence point and the pK_{a} of the **acid** will be found. The melting point of the solid **acid** will be found using a Meltemp.

### Which experimental technique is best used to determine the concentration of an unknown acid?

An acid-**base titration** is an experimental procedure used to determined the unknown concentration of an acid or base by precisely neutralizing it with an acid or base of known concentration. This lets us quantitatively analyze the concentration of the unknown solution.

### How do you find the molecular mass of h2 S o4?

Multiply the **atomic** weight of each element with the number of atoms of that particular element. Similarly, do it for all the elements in the **molecule** or compound. Add up all the values obtained in the above step. Then add the unit as grams/mole you will get the **molecular mass** of the substance.

### What is the molar mass of the solute?

**Mass** of **Solute** and **Molar Mass**

The number of moles of **solute** = **mass** of **solute** ÷ **molar mass** of **solute**, where **mass** is measured in grams and **molar mass** (defined as the **mass** of one mole of a substance in grams) is measured in g/mol. If you don’t know the **mass of the solute**, weigh it on a scale and record the value.

### What is a Diprotic acid Example?

**Diprotic acids**, such as sulfuric **acid** (H_{2}SO_{4}), carbonic **acid** (H_{2}CO_{3}), hydrogen sulfide (H_{2}S), chromic **acid** (H_{2}CrO_{4}), and oxalic **acid** (H_{2}C_{2}O_{4}) have two **acidic** hydrogen atoms. Triprotic **acids**, such as phosphoric **acid** (H_{3}PO_{4}) and citric **acid** (C_{6}H_{8}O_{7}), have three.

### How do you identify a Diprotic acid?

A **diprotic acid** is titrated with NaOH solution of known concentration. Molecular weight (or molar mass) is found in g/mole of the **diprotic acid**. Weighing the original sample of **acid** will tell you its mass in grams. Moles can be **determined** from the volume of NaOH titrant needed to reach the first equivalence point.

### Is water a Diprotic acid?

Re: **Water** as a **polyprotic acid**

**Water** is not a **polyprotic acid** because you would start considering it from H_{2}O and not OH-.

### What is a Diprotic substance?

A **diprotic** acid is an acid that can donate two hydrogen ions (H^{+}) or protons per molecule in an aqueous solution. Another name for a **diprotic** acid is a dibasic acid.
