InterviewSolution

1.	Calculate the total pressure in mixture of 8 g of oxygen and 4 g of hydrogen confined in a total volume aone litre at 27 C
Answer» Moles of O2 = 8/32= 1/4Moles of H2 = 4/2= 2Therefore Total moles of both gas(n) = 1/4 + 2 = 9/4Given :V = 1 dm3T = 300 KR = 0.083 bar dm3 K-1mole-1PV=nRTP = (9 x 0.083 x 300)/(4 x 1) = 56.025 bar
