Mass of gas formula
WebStep 2 (method 1): Calculate partial pressures and use Dalton's law to get \text P_\text {Total} PTotal. Once we know the number of moles for each gas in our mixture, we can now use the ideal gas law to find the partial pressure of each component in the 10.0\,\text L 10.0L container: \text P = \dfrac {\text {nRT}} {\text V} P = VnRT. WebUse the ideal gas equation PV = nRT to calculate n, the number of moles of gas, which is equal to the mass of the gas in the syringe divided by its molar mass in grams. This requires the recording of room temperature and pressure at the time of the experiment.
