A gas mixture contains 0.165 mol C2H6(g) and 0.233 mol O2(g). What is the mole fraction of O2(g) in the mixture
Mole fraction of O2 = 571 Correct The mole fraction is the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture. The mole fractions can be represented in terms of pressures The total pressure PTOTAL = 0.180 atm +0.240 atm = 0.420 atm The mole fraction of CH4 in the mixture PCH 0.180 atm 0.420 atm = 0.429 PTOTAL Since it is the mixture of two gases,...
A gas mixture is made up of O2 (8.14 g), N2 (7.15 g), and CO2 (15.3 g). The mixture has a volume of 25.2 L at 74 °C. Calculate the partial pressure of each gas in the mixture and the total pressure of the gas mixture. PO2 = atm PN2 = atm PCO2 = atm Ptotal = atm
