Problem: The density of a gas is 1.43 g/L at a temperature of 23° C and a pressure of 0.789 atm. Calculate the molar mass of the gas. Express the molar mass to three significant figures and include the appropriate units.

FREE Expert Solution

We’re being asked to calculate for the molar mass of a gas with a density of 1.43 g/L at 23°C, 0.789 atm

To calculate using density, we’re going to use the ideal gas equation.

PV=nRT


PVV=nRTV

P=nRTV

n=mass mmolar mass (M)
