Write and balance the three steps as equations.
Convert 118 kg isobutylbenzene to mols. mols = grams/molar mass = ?
Use the coefficients in the balanced equation to convert mols isobutylbenzene to mols ibuprofen. Multiply by 0.24, then convert mols of product to grams. g = mols x molar mass.
At the start of the process 118 kg of isobutylbenzene is used and the overall yield of the 3 reaction steps is 24%, how many 400 mg tablets of ibuprofen will be produced?
Isobutylbenzene:
Chemical formula = C10H14
Molecular Weight = 134.22g
2-(4-isobuytlphenyl) propanoic acid
Chemical Formula = C13H18O2
Ibuprofen
