# Does a mole of hydrogen have the same mass as a mole of oxygen?

Contents

Does a mole of hydrogen have the same mass as a mole of oxygen? Explain your answer. No, a mole of oxygen atoms will have a larger molar mass than a mole of hydrogen atoms, simply because oxygen atoms are more massive.

## Which has more mass hydrogen or oxygen?

The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1.

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

One MOLE of hydrogen atoms contains the same number of atoms as the number of hydrogen molecules in one MOLE of hydrogen molecules, i.e., Avagadros number. However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.

## What is the mass of one mole of oxygen?

One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 1023 atoms of oxygen.

## Does a mole of carbon have the same mass as a mole of hydrogen?

One mole of carbon atoms is approximately 12 times heavier than a mole of hydrogen atoms.

## What is the 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.
