Question

calculate the vapour density of a gas if its density with respect to ch4 is 4

pls give appropriate answers with solutions​

Answer 1

Answer:

64

Explanation:

The molecular weight or the molar mass would be 64 because vapor density is related with molecular mass as

molar mass 2×V.D

In methane CH4 molar mass =16

Thus vapor density =162=8

Here relative vapor density is 4 for the substance so it is =8×4=32

Hence Molar mass of the substance =2×32=64
