Unformatted text preview: d ) of a gas can be determined according to the following: • Alternatively, if the density of the gas is known, the molar mass of a gas can be determined: Example: What is the density of carbon tetrachloride vapor at 714 torr and 125°C? The molar mass of CCl 4 is 12.0 + (4*35.5) = 154 g/mol. 125°C in degrees Kelvin would be (273+125) = 398K. Since we are dealing with torr, the value of the gas constant, R, would be 62.36 L torr/mol K....
