Putting values in equation 1, we get: Hence, the mass of acetic anhydride reacts is 2.25 grams. Firstly, we determine the molar mass of reactants and products: th e molar mass of salicylic acid M( C7H 6O 3)=138.12 g/mol; the molar mass of acetic anhydride M( C4H 6O 3)=102.09g/mol; the molar mass of aspirin M( C9H 8O 4)=180.16g/mol. mass of aspirin = ? - excess amount of C4H6O3 - Molar mass of C9H8O4 = 180.157g/mol - C7H6O3 molar mass - 138.121 g/mol. However, we can still go through the solution step by step and see how the molarity of the acetic anhydride solution can influence what is going on. WDJHALXBUFZDSR-UHFFFAOYSA-N Copy. Calculate for the molar mass of the compound and use dimensional analysis to determine the number of moles . Since the equation is already balanced, you start by converting the 305g into moles of reactants by dividing it by the molar mass. The balanced equation tells us that the two chemicals above react in a 1:1 molar ratio. I can't just assume that the density of C4H6O3 is 1g/mL because it's not water, and the problem doesn't say to assume its density to be the same as water. 0.0151 moles of aspirin × 180.16 g/mol C9H8O4 = 2.720 grams of aspirin. Therefore. 13.5 kg C9H8O4 b. your answer, rounded to 3 sig figs is.
