STANDARD Chemistry Gas Density and Molecular Weight MCQ 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:
1/2
2/3
3/4
2
Correct Answer
Detailed Explanation
Using the ideal gas equation and the given conditions, the ratio of molecular weights can be derived. The pressure and density relations lead to the conclusion that the molecular weight ratio is 3/4.
