The density of acetic acid vapour at 300 K and 1 atm is 5 mg `cm^(-1)`. The number of acetic acid molecules in the cluster that is formed in the gas phase is closest to

A

5

B

2

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
`PM=rhoRT`
`M=((5xx0.0821xx300)/(1))=123.15`
`:.` Number of acetic acid molcule =`(123.5)/(60)~~2`
