A 19.51 g sample of impure methylamine, which contains 72.58% (by mass) of CH;NH2 , is reacted with 30.81 g of pure oxygen gas: 4CH3NH2 (g) + 902(g) → 4C02(g) + 10H20(f) + 2N2(g) 1 What is the percentage yield of this reaction if 5.54 g of nitrogen gas is collected? 2 In another experiment, this impure methylamine was used as follows: • An unknown mass of the impure compound is dissolved in enough water to make 500.0 mL of solution. • 20 ml of this solution was transferred by pipette to a clean 250 mL volumetric flask and made up to the mark. • The molarity of the CH;NH, in the final solution was determined to be 0.103 M. Determine the mass of CH;NH2 present in the original amount of impure compound used to make this solution.
