# What is the mass of 0 2 mole of atom?

Contents

-To calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.

## What is mass of 0.2 mole of oxygen?

(a) Mass of one mole of oxygen atoms = 16 g. Then, the mass of 0.2 mole of oxygen atoms = 0.2 x 16g = 3.2 g.

## What is the mass of 0.2 mole of water molecules?

∴ 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g (b) 1 mole of water molecules = 18 g ∴ 0.5 mole of water molecules = 18 × 0.5 = 9 g 10.

## What is the mass of 0.2 mole of chlorine gas?

Chlorine gas Cl 2, has a relative molecular mass of 71 because it is made up of two Cl atoms, each of Mr 35.5. A mole of chlorine gas has a mass of 71g, and contains two moles of chlorine atoms, each of mass 35.5g.

## What is the mass of 0.5 mole of oxygen atom?

(i)0.5 mole of oxygen gas. (ii) 3.011 x 1023 atoms of oxygen. (iii) 6.022 x 1024 molecules of oxygen. (Given atomic mass of 0 = 16u; No = 6.022 x 1023 per mole)
