## How do you get 1 mole of hydrogen?

Mass of 1 mole of hydrogen atoms = Mass of 1 hydrogen atom×NA , where NA=L=6.0225×1023⋅mol−1 .

## What is the mass of 1 gram of hydrogen?

A gram molecule is the number of molecules present in one mole of that substance, instead of the atoms. The weight of 1 atom of hydrogen is calculated as 1.66058 × 1024 grams.

## How many moles are in 1 kg of H2?

To make up for 1 kg hydrogen or 1000 gm of hydrogen gas, we need 500 moles of hydrogen gas. These many moles of hydrogen gas will have atoms (500 times the Avogadro’s number of atoms).

## What is the mass of 1 mole of diatomic hydrogen H2?

Diatomic hydrogen has a molecular mass of 2.0 amu. One mole of hydrogen gas has a mass of 2.0 grams.

## What is mass of 5 moles of hydrogen gas?

Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = 10.08 g.
