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 76 5 mL 15 Sketch of a gas collection apparatus collected gas water chemical reaction Calculate the mass of CO that is in the collection tube Round your answer to 2 significant digits You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases
