14.0 g of acetylsalicylic acid were obtained from 23.9 g of salicylic acid. Determine the percentage yield of acetylsalicylic acid. What I did: 23.9 g ÷ 138 g = 0.1732 mol Known Information: Reactant mass: 23.9 g Product mass: 14.0 g Reactant moles: 0.1732 moles *Please help: How would I solve for the Theoretical maximum moles of acetylsalicylic acid? acetylsalicylic acid C₉H₈O₄ (12•9) + (1•8) + (4•16) = 180 g/mol Would it be 14.0 g ÷ 180 g? Please explain.

Next you convert grams to moles using the molar mass of the starting material in this case coal. I'm going to change the number up slightly so that I don't give away the answers but the final answer we get will be close to the correct answer to the original question. The formula for coal is C135H96O9NS. On anxam that formula will be given to you. Calculate the molar mass from the formula and use the molar mass as a...

This is bromination of toluene lab, and the question asks how did the calculated moles of toluene correspond by mass and volume? if they are significantly different, which do you think is more accurate? moles of toluene from mass= 1.58*10^-3 moles of toluene from volume= 1.08*10-3 I'm not sure how to answer this question. Any help? experimental data: mass toluene from mass=0.146g mass of toluene from volume= 0.0996g volume of toluene used=0.115mL
