The van der Waals constant for gases `A`, `B`, and `C` are as follows

Answer the following:
Which gas has the largest molecular volume?

Options

A. `A`
B. `B`
C. `C`
D. None

Explanation

Since molecular volume `V=3b`
For gas `A=V_(A)=3xx0.027=0.069 dm^(3)`
For gas `B=V_(B)=3xx0.030=0.090 dm^(3)`
For gas `C=V_(C)=3xx0.032=0.096 dm^(3)`
`:. V_(C)gtV_(B)gtV_(A)`
