The numbr of atoms in 0.1 mole of a triatomic gas is _______________.`(N_(A)=6.02xx10^(23)"mol"^(-1))`

A

`1.800xx10^(22)`

B

`6.026xx10^(22)`

C

`1.806xx10^(23)`

D

`3.600xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
C
No. of atoms = No. of molecules `xx` atomicity
`0.1 N_(A)xx3=0.1xx6.02xx10^(23)xx3=1.806xx10^(23)`
