Homework Statement
Calculate the theoretical yield of aspirin (C9H8O4).
C7H6O3 + C4H6O3 --> C9H8O4 +C2H4O2
Mass C7H6O3 = 2g
Volume C4H6O3 = 4mL
Homework Equations
The Attempt at a Solution
I am not sure where to go with this prolem at all. 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. All I could do was find the molar mass of each substance:
C7H6O3 = 138.13g/mol
C4H6O3 = 102.1g/mol
C9H8O4 = 180.17g/mol
C2H4O2 = 60.06g/mol
I also know that I have to find the limiting reagent, to actually determine the mass of C9H8O4, but doing that requires some more information. I know that I can just Google the density of C4H603, but if its not given in the problem then its assumed that there is another way. From what I know about calcualting the limiting reagent, you need either:
(1) mass reactant / molar mass reactant --> we don't have the mass of C4H603
OR
(2) volume reactant * density reactant / molar mass reactant --> we don't have the density of C4H603 either
So with the information provided, I have no idea how to calculate the mass of C9H8O4 (aspirin)
