25 g of each of the following gases are taken at `27^@C`and 600 mm pressure. Which of these will have the least volume?

A

`HBr`

B

`HCl`

C

`HF `

D

`HI`

Text Solution

Verified by Experts

The correct Answer is:
D
Ideal gas equation is PV = nRT If pressure and temperature is same for all the gases then VC (from above equation) n = no. of moles of the gas ` = (wt)/(M.wt)` (here weight of all gases are equal) `therefore V prop 1/(M.wt)` the options, Hl has more molecular weight than remaining gases, so it has least volume,
