Question

the no. of atoms in 0.1 mole of a triatomic gas is. (a) 1.8×10^22 (b)6.026×10^22 (c)1.806×10^23 (d)3.6×10^23​

Answer 1

Answer:

1.806×10^23 atoms

Explanation:

the atomicity of the gas is given

triatomic , so it has 3 atoms in one molecule

so in 0.1 mol of the gas

it has 0.1×3 mol of atoms in 0.1 mol of the triatomic

gas molecule

0.1×3=0.3mol=0.1×6.02×1=1.806×10^23 atoms
