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 O₂ gas evolved by a certain chemical reaction taking place at 50.0 °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 43.9 ml.. 5 Sketch of a gas-collection apparatus collected gai water Calculate the mass of O, 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. chemical
