A small company is planning to synthesize commercial aspirin and has hired you as their consultant to aid in the production line. You need to purchase the required amount of reagents, i.e. acetic anhydride, salicylic acid, and the phosphoric acid catalyst. The planned pilot plant is tasked with preparing 250 g of aspirin. If the established percent yield for the reaction is 83.6%, how many grams of salicylic

One night you and your friend decided to help in agriculture. The farmer you are helping reacted 90 Kg of Calcium fluoride phosphate (Cas(PO4)3F) and 30L of sulfuric acid(H2SO4), so far he has collected 5Kg of hydrofluoric acid (HF) and the farmer wants to know the % yield of the HF to estimate the time needed to complete the reaction.
