To simplify calculations and reporting, the units used in the problem will be molecule X Incorrect: Try Again; 3 attempts remaining First, identify the limiting reactant, which is the substance that is completely consumed during the reaction. You can then determine how much product is produced using the ratio of the limiting reactant to the desired product You may want to review Hint 1. How to approach the problem.
Consider a reaction in which two reactants make one product (for example, consider the unbalanced A + B → C). You know the following: 2.0 mol A (with an excess of B) can make a maximum of 4.0 mol C 3.0 mol B (with an excess of A) can make a maximum of 8.0 mol C If you react 2.0 mol A and 3.0 mol B, what is the maximum amount of C that can be produced?
