If `0.24 g` of a volatile liquid upon vaporization gives `45 ml` of vapors at `NTP`, what will be the vapor density of the substance? (Density of `H_(2) = 0.089 f L^(-1)`)

A

95.39

B

39.95

C

99.53

D

59.93

Text Solution

Verified by Experts

The correct Answer is:
D
Density of vapours of volatile liquid at NTP
`=0.24/45 g mL ^(-1)`
`=0.24/45 g mL ^(-1)`
`=0.24/45xx10^3 gL ^(-1)= 240/45 gL^(-1)`
=Vapour density
`("Dendity of gas / vapour ")/("Density of H_(2)(Similar T & P))`
`=(240//45)/(0.089)=(240000)/(89 xx 45)=59.93`
