The experimental setup used in this lab was used to study a reaction which generated CO2 gas. During the reaction, 0.159 g of gas was generated and 94.1 ml of water was displaced. The experiment was then repeated with a reaction which generated N2 gas. If 0.212 g of N2 gas was generated, what volume, in ml, of water was displaced? Assume all gas generated results in water displacement and no change in P or T between experiments. (Use three significant figures in your answer)
