A flask filled with `C Cl_(4)` was weighted at a temperature and pressure. The flask was then filled with oxygen at the same temperature and pressure. The mass of `C Cl_(4)` vapour would be about

A

same as that of oxygen

B

`1//5`th as heavy as oxygen

C

5 times as heavy as oxygen

D

twice as heavy as oxygen

Text Solution

Verified by Experts

The correct Answer is:
C
The mol. Mass of `C Cl_(4) = 12 + 71 xx 2 = 154` Whereas that of oxygen = 32. Hence `C Cl_(4)` is approximately 5 times heavier than oxygen
