Determining Maximum Production from a Chemical Reaction

A certain chemical reaction takes place in a closed container where 2 moles of substance A react with 1 mole of substance B to produce 3 moles of substance C. The reaction can be represented as follows:

2 A + B → 3 C

If you start with 4 moles of substance A and 3 moles of substance B, what is the maximum amount of substance C that can be produced?
