Calcuating the mole ratio?

[JM92]

Homework Statement

We are given the fact that 0.12 mol NaOH reacts with 0.015 mol methyl salicylate (C₈H₈O₃) to form disodium salicylate (C₇H₄Na₂O₃). We're asked to calculate the mole ratio of NaOH to C₈H₈O₃, identify the limiting reagents, and find the theoretical yield.

The Attempt at a Solution

I thought I could just divide the mole values given and get 8 NaOH :1 C₈H₈O₃, but the equation doesn't make sense in those ratios.

(I also found out through Google that water H₂O and methanol CH₃OH are byproducts of the reaction, but that wasn't given to us so maybe it's irrelevant to solving the questions. Anyway, if we consider the byproducts, the mole ratio I want would be 2 NaOH : 1 C₈H₈O₃).

Would the only way to answer this be to figure out the balanced equation?

Yes, you must figure out the balanced chemical equation, especially if you want to find the limiting reagent in this reaction and calculate the theoretical yield. The Magic 8 Ball will be no help to you here.

An excellent start.
