- 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 CO₂ 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 87.0 mL. collected gas X water chemical reaction Sketch of a gas-collection apparatus Calculate the mass of CO₂ that is in the collection tube.
