Calculate the mole fraction of nitrogen gas in a 15.00 L gas cylinder at 29.00°C with 2.300 moles of carbon dioxide and 5.700 moles of nitrogen gas.

Homework Answers

Answer #1

no of moles of N2 nN2 = 5.7 moles

no of moles of CO2 nCO2 = 2.3 moles

total no of moles of N2 and CO2 = 5.7 + 2.3   = 8 moles

mole fraction of N2 XN2   = nN2/nN2 + nCO2

                                           = 5.7/5.7 +2.3    = 5.7/8   = 0.7125 >>>>answer
