A 0.5 dm^3 flask contains gas A and 2 dm^3 flask contains gas B at the same temperature. If density of A = 4 g/dm^3, that of B = 2 g/dm^3 and molar mass of A is half of that of B, then the ratio of pressure exerted by gas is

Answer»

`P_A/ P_B = 0.5`
`P_A/ (P_B) = 2`
`P_A/ (P_B) = 4`
`P_A/ (P_B) = 0.25`
