Calculating the mass of a gas collected over water
Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch
at right). This makes it easy to isolate and measure the amount of gas produced.
Suppose the CO gas evolved by a certain chemical reaction taking place at 40.0 °C is
collected over water, using an apparatus something like that in the sketch, and the final
volume of gas in the collection tube is measured to be 63.9 mL.
