The number of atoms in 0.1 mol of a triatomic gas is : `(N_A = 6.02 xx 10^23 "mol"^(-1) ) `

A

`3.600 xx 10^23`

B

`1.800 xx 10^22`

C

`6.02 xx 10^22`

D

`1.806 xx 10^23`

Text Solution

Verified by Experts

The correct Answer is:
D
No. of moleculesin 0.1 mol ` = 0.1 xx 6.02 xx 10^23`
No. of atoms ` = 0.1 xx 6.02 xx 10^23 xx 3`
` = 1.806 xx 10^23`
