# Frequent question: What is the mass of 1 mole H2?

Contents

The mass of one mole of H2 is 2.01588 grams but some sources also list it as 2.016 grams.

## What is the mole of H2?

H2 – There are 2 moles of hydrogen atoms (1 mole of elemental hydrogen).

## How do you find one mole of H2?

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

## How many grams are in 1 mole of hydrogen?

An amount of any substance in grams that is numerically equal to its atomic or molecular weight in amu has been defined as one mole of that substance. By this definition, one mole of hydrogen is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams.

## How many moles are in 10g of H2?

## How many moles are in 5g of H2?

The answer is 2.01588. We assume you are converting between grams H2 and mole. You can view more details on each measurement unit: molecular weight of H2 or mol The SI base unit for amount of substance is the mole. 1 grams H2 is equal to 0.4960612734885 mole.

## What is the mass of 2 mole of CO2?

The mass number of CO2 = 2×16 + 12 =44 so one mole of C02 has a mass of 44g. Two moles of CO2 weighs 2 x 44 = 88g.

## How many atoms are there in 1 mole of H2?

Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule. Thus we must multiply 6.022 * 1023 by 2 to calculate the number of individual atoms present in 1 mole of H2. We find our answer to be 1.2044 * 1024.

## How did Avogadro find the mole?

The term “Avogadro’s number” was first used by French physicist Jean Baptiste Perrin. … If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.02214154 x 1023 particles per mole.
