## Frequently Asked Question:

### What is the percent by mass of hydrogen?

8889), and note that the sum of the fractions is 1. The percentage of an element in a compound is 100 times the fraction, so for water the mass percent hydrogen is **11.11%** and the mass percent oxygen is **88.89%**.

### How do you calculate percent by mass?

**Mass Percentage Formula**

- mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100. The formula for a solution is:
- mass percent = (grams of solute / grams of solute plus solvent) x 100. or.
- mass percent = (grams of solute / grams of solution) x 100. The final answer is given as %.
