Calculations Using Standard Molar Volume - …

Using this information, the volume occupied by any nuer of moles (or grams) can be determined. Conversely, the nuer of moles present in any volume of gas at STP can also be determined, and if the identity of the gas is known, this nuer of moles can be converted to a mass. Standard molar volume is also useful for Density determinations at STP.
