## What is meant by 1 mole of hydrogen atom?

The definition of Avogadro’s number of 6.022 × 10^{23}/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains **6.022 × 10 ^{23} hydrogen atoms**.

## What is the mass of one mole of hydrogen molecules quizlet?

The formula for molecular hydrogen is 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 the mass of 2 moles of H2?

1 mole of hydrogen gas weighs 2 gram so 2 moles weigh **4 grams** mate hope this helps.

## What is the mass of 5 moles of H2?

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**.

## What is the mass of 1 hydrogen atom in grams?

We now know that a hydrogen atom has a mass of **1.6735 x 10 ^{–}^{24} grams**, and that the oxygen atom has a mass of 2.6561 X 10

^{–}

^{23}grams.

## How do you find the mass of one hydrogen atom?

This means that 1 MOLE of hydrogen atoms will weigh 1.008 grams. That said, to find the mass of one ATOM, we need to convert from moles to atoms as follows: 1.008 grams/mole Hydrogen * (1 mole/6.022×1023 atoms) = **1.67 x 10-24 grams**. Hence, it’s possible to calculate the mass of one Hydrogen atom in gram.
