A piece of magnesium ribbon is massed and placed into a sealed flask containing dilute HCl as shown above. Once the reaction is complete, the tube is adjusted to that the water in the tube
is level with the water in the trough and the volume of gas is recorded as 25.50 ml. The
atmospheric pressure in the room is recorded as 765.5 mmHg at a temperature of 23°C. The
vapor pressure of water at 23°C is 21.1 mmHg
