## Chemistry: A Molecular Approach (3rd Edition)

Determine the limiting reactant. Choose one of the reactants and determine how much we need compared to how much is available. We choose to compare Na. $2$ $mol$ $Na(avaliable)$ $2 mol Br_{2}$$\times\frac{2 mol Na}{1 mol Br_{2}}$ $=4$ $mol$ $Na (needed)$
