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 gas evolved by a certain chemical reaction taking place at 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. Sketch of a gas-collection apparatus calculate the mass of that is in the collection tube. Round your answer to significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases.
