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

A

`1.806 xx 10^(23)`

B

`3.600 xx 10^(23)`

C

`1.800 xx 10^(22)`

D

`6.026 xx 10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
A
Number of atoms
= number of moles `xx N_(A) xx` atomicity
`= 0.1 xx 6.02 xx 10^(23) xx3`
`= 1.806 xx 10^(23)` atom
