A common laboratory technique is to collect gas from a chemical reaction by what is called water displacement. In water displacement, the volume of the gas collected is equal to the volume of water
that is displaced from the container. Unfortunately, the gas collected is not entirely limited to the gas
released from the reaction. Because of the presence of water, a small amount of water vapor
contaminates the gas sample. What is the pressure of the gas produced in the reaction if the
atmospheric pressure at 29°C is 802 mmHg?
