The density of a gaseous organic compound is 3.38 g/l at 40 degrees and 1.97atm. What’s the molar mass

Asked by lizamie9803

Answer (1)

Assuming that the gas is an ideal gas, use the ideal gas equation PV = nRT to solve for the molar mass.Rearranging the ideal gas equation:[tex]M = \frac{dRT}{P}[/tex]where M - molar mass, R - ideal gas constant, T - temperature (in Kelvin), and P - pressureUsing the given and the ideal gas constant = 0.0821 Latm/molK[tex]M= \frac{3.38*0.0821*313.15}{1.97} \\M = 44.1406 g/mol[/tex]
