Sample Problem

Consider this reaction: 2A + B → 3C + D

3.0 moles of A and 2.0 moles of B react to form 4.0 mol of C. What is the percent yield of this reaction? (Round to the nearest whole number)

%

Solution

First, we need to determine the limiting reactant.

Therefore A is the limiting reactant

Second, we need to decide the number of moles of C produced.
