Purpose:To determine experimentally the volume of 1 mole of hydrogen gas at STP. Materials and Equipment: gas-measuring tubelarge deep container for equalizing gas pressure in tube one-hole stopper10-mL graduated cylinder ring standmetric ruler ...
molar volume,the volume occupied by amoleof a substance atSTP. According to Avogadro's law, at a given temperature and pressure a given volume of any gas contains the same number of molecules. At STP 1 mole of gas occupies 22.414 liters. This volume is what is usually meant by the mola...
We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but the molar mass of the gas can also be calculated from the same equation. Like any other calculations with the molar mass...
