The charles law constant under the lab conditions is • mass of 1 mole of a gas is its molar mass • volume of 1 mole of gas depends on t lab 1 molar volume. The volume occupied by one mole of a gas is known as its molar volume all gases that behave ideally have the same molar volume at the same conditions of temperature and pressure for convenience, the molar volume is generally referred to standard conditions of 273 k and 760 torr. Molar volume of the ideal hydrogen gas at room temperature (volume/moles), expressed as l/mol at x degrees c and a pressure of 1 atmosphere = 224 l/mole 000382 moles = 00856 l or 856ml 2 for the second part of the experiment, everything was the same except that twice as much zn was used.
Gas would occupy the same volume as one mole of any other ideal gas at the same temperature and pressure the volume occupied by one mole of a gas is the molar volume. The molar volume of a gas in this experiment, you will determine the molar volume of a gas by conducting a chemical reaction that produces a gas, as shown in the reaction equation below.
