Sometimes in lab we collect the gas formed by a chemical reaction over water (sce skerch at pight), This makes it easy to isolate and measure the amount of gas produced. Suppose the $${\mathrm{CO}}_2$$ gas evolved by a certain chemical reaction taking place at 55.0 . $$\mathrm{C}$$ is collectid over water, using an apparatus something like that in the sketch, and the final volume of gas in the coliection tube is meosured to be $$99,9\mathrm{mL}$$. Calculate the mass of $${\mathrm{CO}}_2$$ that is in the collection tube. Round your answer to 2 significant digits You can make afyy norrmal and reasonable assumption about the reaction conditions and the nature of the gases.
