If 0.02 g of a volatile compound on heating displaces 11.2 ml of dry air at STP, the molecular weight of the compound is

A

20

B

30

C

40

D

50

Text Solution

Verified by Experts

The correct Answer is:
C
11.2 ml of dry air at STP displaced by 0.02 gm
22400 no of air at STP displaced by 0.02 m
`(22400xx0.02)/(11.2)=40 therefore` molecular weight = 40
