0.24 g of a volatile gas , upon vaporisation gives 45 mL vapour at NTP . What will be the vapour density of the substance ? (Density of `H_(2)=0.089)`

A

9.539

B

59.93

C

5.993

D

95.39

Text Solution

Verified by Experts

The correct Answer is:
B
It is an example of victor Meyer's method
`Mw=("mass of compound "xx22400)/("volume of vapours at STP")`
`=(0.24xx22400)/(45)=119.46`
Vapour density `=(Mw)/(2)=(119.46)/(2)=59.7`
