Question

Density of two gases are in the ratio 1:2 and their temperatures are in the ratio 2:1, then the ratio of their pressures is:

Answer 1

Answer : Ratio of Pressures = Reciprocal of Ratio of Their Corresponding Molecular Weights.

We Know that P = dRT/M

Where P= Pressure, d=density, R=Gas Constant, T=Absolute Temperature, M =Molecular Weight
