# Question

The density of a pure gaseous compound was measured at 0.00oC as a function of pressure to give the following results:
Density (g/ L) ........... Pressure (atm)
0.17893 ................................................... 0.2500
0.35808 .................................................... 0.5000
0.53745 ..................................................... 0.7500
0.71707 ................................................. 1.000
Calculate the molar mass of this compound, corrected for any nonideal behavior of the gas. Assume the non­ideal gas obeys the equation PV/ nRT = 1 + bP.
