The number of atoms in 0.1 mol of a triatomic gas is `(N_A = 6.023 xx 10^(23) mol^(-1))`

A

`6.023 xx 10^(22)`

B

`1.806 xx 10^(22)`

C

`3.600 xx 10^(23)`

D

`1.800 xx 10^(22)`

Text Solution

Verified by Experts

The correct Answer is:
B
No of atoms ` = N_A xx `No . Moles `xx` 3 ( atomicity )
`= 6.023 xx 10^(23) xx 0.1 xx 3 =1.806 xx 10^(23)`
