Problem: Calculate the molar mass of a vapor that has a density of 7.135 g/L at 13 oC and 744 torr .

FREE Expert Solution

We are asked to calculate the molar mass of a vapor that has a density of 7.135 g/L at 13 oC and 744 torr.



Given: 

P = 706 torr = 0.979 atm

T = 13 oC +273.15 = 286.15 K

R = 0.08206 L-atm/mol-K

d = 7.135 g/L
