How many grams of salicylic acid can be produced from 4.0 millimoles of methyl salicylate?

Answer 1

Since methyl salicylate is the limiting reactant (hydrolysis reaction) and the reaction occurs in a one to one ratio. Since it's 1:1, theoretically, 4.0 mmol of methyl salicylate should produce 4.0 mmol of salicylic acid.

If your reaction goes 100%, then you will produce 4.0 mmol of salicylic acid or 0.004 mol. Multiply the number of moles by the molecular weight of salicylic acid (138.12 g/mol) and you will have your theoretical grams that can be produced.

0.004 mol * 138.12 g/mol = 0.5525 g or 552.5 mg
