Need uber chemist to calculate the limiting reagent

[iLoveDivX]

The chemical equation is (C7H6O)2 + C3H6O ========> C17H14O + H2O + OH + H

Molecular weight of (C7H6O)2 is 106.13 grams
Molecular weight of C3H6O is 58.08 grams

I used .212 grams of (C7H6O)2
and .058 grams of C3H6O

I need to find which one is the limiting reagent. I can normally do this but forgot what to do when the chemical equation uses two moles of a certain reactant [ie (C7H6O)2]. do i need to divide my answer by two or multiply? thanks

2:1 ratio of first reactant to second reactant. Limiting reagent is second reactant.

Please note that this is a shortened version. Actually calculations may result in a different answer.😉

Figure out the molar equivalents of each of the reactants. The one with the lower equivalent value is the limiting reagent.
