re and pressure (STP)? At STP, the molar volume of an ideal gas is 22.4 liters per mole. To calculate it for a specific gas, you can use the ideal gas law: V = nRT/P, where n is moles, R is the gas constant, T is temperature,
Using precise instruments, such as gas burettes, volumetric flasks, and manometers. Typical procedure: Collect a known mass of gas. Measure the volume it occupies at known temperature and pressure. Calculate moles from the mass or pressure-volume relationship. Determine molar volume a
