Question

The density o gas a is twice that f gas b at the same temperature. the molecular weight of gas b is thrice that of gas



a. the ratio of pressure acting on a and b are

Answer 1

ratio of pressures is 6:1

Answer 2

Keeping conditions CONSTANT as mentioned in the question we get an equation  PM= dRt  P(a)= 2*d(b)Rt/M(a) P(b)= d(b) Rt/ 3*M(a) Taking Ratio  We get  6:1
