Question

A gaseous mixture of 2 moles of A, 3 moles of B, 5 moles of C and 10 moles of D is contained in a

vessel. Assuming that gases are ideal and the partial pressure of C is 1.5 atm, find the total pressure.

10) Two gases A and B having same volume diffused through a pinhole in 10 and 5 seconds respectively.

The molecular weight of A is 48. What would be the molecular weight of B?

11) At a certain altitude, the density of air is 1/10th of the density of the earth's atmosphere and temperature

is -10°C. What is the pressure at that altitude? Assume that air behaves like an ideal gas, has uniform

composition and is at S.T.P. at the earth's surface.​
