For any gas, these speeds can be calculated by the following formulas: where \(T\) is the kelvin temperature, \(R\) is the gas constant expressed in units of J/mol-K (8.314 J/mol-K), and \(M\) is the molar mass of the gas expressed in units of kg/mol. The momentum of an object is the virtue of its mass. and it's measured in hours along the horizontal axis. Refer back to the snap lab and the simulation lab.
