Question

A gaseous mixture of three gases A, B and C has a pressure of 8 atm. The total number of moles of all the gases is 8. If the partial pressures of A and B are 2.0 and 2.0 atm, respectively, and if C has molecular mass of 4.0, what is the mass of C, in g, present in the mixture?

Options:

Answer:

D

Solution:

p_C = 8 - 2 - 2 = 4 atm, so x_C = 4/8 = 0.5 and n_C = 0.5 × 8 = 4 mol. Mass of C = 4 × 4.0 = 16 g. Confirms Ans: (d) 16.
