Question

Rthe vapour density of two gases are in the ratio of 1:3. Their molecular masses are in the ratio of

Answer 1

Answer:

The vapour densities of two gases are in ratio 1:3 . Their molecular masses are in ratio of: (1) 1:3 (2) 1:2 (3) 2:3 (4 ) 3:1

Answer 2

Explanation:

Vapour density = 2 × Molecular mass

So, According to the question,

Ratio of molecular mass = Ratio of vapour density = 1:3

If the vapour density is in the ratio of 1:3,their molecular masses will also be in the ratio of 1:3.Hope this would be helpful.
