Question

Two vessels separately contain two ideal gases A and B at the same temperature. The pressure of A being twice that of B. Under such conditions, the density of A is found to be 1.5 times the density of B. The ratio of molecular weight of A and B is:(a) $\frac{3}{4}$(b) 2(c) $\frac{1}{2}$(d) $\frac{2}{3}$

Answer 1

I think (b) because the gas was evaluated is hydrogen

Answer 2

Answer:3/4

Explanation:

P=dRT/M

M=dRT/M

Ma/Mb=da/db*Pa/Pb

On solving by adding numericals...we get 3/4
