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 144. mL.Calculate the mass of O₂ 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.---**Explanation of the Diagram:**The image shows a gas-collection apparatus. It includes:- A flask where the chemical reaction occurs, producing gas.- A delivery tube connecting the flask to a gas collection container submerged in water.- The gas collection container captures the collected gas as it is released from the reaction flask. The pressure from the water helps isolate and measure the gas volume accurately.This method is useful for capturing gases that are not soluble in water, such as oxygen, and allows for an accurate measurement of the gas volume produced during a chemical reaction.
