## What is the mass of 0.1 moles of oxygen?

Mass of 0.1 mole of oxygen is = 16 * 0.1 =1.6 g.

## What is the mass of 1.0 mole?

This can also be written as 6.022×1023 mol1. The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## What is mass of 1 molecule of oxygen?

O2 is a diatomic molecule. … ∴ Mass of O2 molecule = 2 × 16 = 32 amu. Mass of one molecule of oxygen. ⇒ 32/ Avogadro constant ( 6.023 × 1023) ⇒ 5.31 × 1023g.

## What will be the number of oxygen atoms in 0.1 mole of O2?

A mole of oxygen molecules contains 2 moles of oxygen atoms. Thus “1 mole of oxygen molecules” means 6.022 x 1023 O2 molecules, or 2 x 6.022 x 1023 O atoms; “1 mole of oxygen atoms” means 6.022 x 1023 O atoms.

## What is the mass of 0.5 mole of ozone molecule?

Atomic mass of oxygen is 16. One ozone molecule contains 3 O-atoms. So molecular weight of ozone would be 16×3 = 48 g/mol. Therefore, weight of 0.5 mol of ozone is 24 g.

## How do you find the mass of oxygen?

Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.
