# What is the mass of H in one mole of H2SO4?

Contents

Notice that you have two hydrogen atoms per formula unit of sulfuric acid. This means that one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol . This means that every mole of sulfuric acid has a mass of 98.0795 g .

98,079 г/моль

## What is the percentage of H in H2SO4?

Answer. Percent of hydrogen in sulfuric acid is 2.055%. oxygen-65.251% and sulfur- 32.693%.

## How do you find moles of H?

Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
