Formula for moles of a gas

WebThe molar volume of gas at STP, standard temperature and pressure (0°C or 273K, 100 kPa pressure) is 22.4 litres per mole (22.4 L/mol). In other words, one mole of atoms of a pure ideal gas at 0°C will fill 22.4 litres of space. The molar volume of gas at room temperature (25°C, 298K) and pressure is 24 litres per mole (24 L/mol). Webvolume of gas = moles × Vm rearranging this: \ [moles~of~gas = \frac {volume} {V_m} \] The volume of gas and the Vm are always in the same units. If you are using a gas …
