Lab Report Devon Corcoran Chem. II Lab Dr. Ward Molar Volume of a Gas Introduction Avogadro’s Law states that the volume of a gas is proportional to the number of moles of gas present provided that pressure and temperature are held constant; V n . Also, kV n = . Avogadro also observed that one mole of any gas should occupy 22.4 liters at standard temperature and pressure. Standard temperature and pressure is 0 ° C (273.2 K) and 1 atm (760 torr, 760 mmHg) of pressure. The purpose of the experiment, Molar Volume of a Gas , is to verify Avogadro’s molar volume observation by producing a known number of moles of hydrogen gas, measuring its volume, and then determining the molar volume. Experimental A water trough was filled approximately half full of water. The water was allowed to equilibrate to room temperature and monitored with a thermometer. A piece of magnesium ribbon was obtained and weighed. Its mass was recorded. The ribbon was coiled to fit inside the eudiometer tube, and tied to a piece of thread. Approximately 10 mL of 6 M HCL was poured into a beaker and then into the eudiometer tube. The eudiometer tube was then filled all the way to the top with distilled water. After filling, the magnesium coil was placed in the tube, the stopper was put on the tube so that it was holding the thread in place, and it was flipped over in a test tube holder
