Question

the number of atoms in 0.2 mole of diatomic gas is

Answer 1

Answer: 2.41 × 10^23 atoms are present in 0.2 moles of a diatomic gas.

Explanation:

The number of atoms present in 1 mole of a gas = 6.023 × 10^23

Since the gas is diatomic( 2 atoms present in a mole), the number of atoms present = 6.023 × 10^23 × 2

Therefore, the number of atoms present in 0.2 moles of the gas = 6.023 × 10^23 × 2 × 0.2 = 2.41 × 10^23 atoms

So, the required answer is 2.41 × 10^23 atoms.
