# What is the mass of 0 2 moles of oxygen atom 0 16gm?

Contents

Answer : (a) The atomic mass of oxygen (O) = 16 u. The mass of 1 mole of oxygen atoms = 16g. Hence, 0.2 mole of oxygen atom = 3.2 g.

## What is the mass of O 2 mole of oxygen atoms?

-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.

## How do you find the mass of 0.2 mole of oxygen atom?

9. What is the mass of : (a) 0.2 mole of oxygen atoms? (b) 0.5 mole of water molecules? Ans. ∴ 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.
