Based on the balanced equation below, how many moles of SF6 can form from the combination of 6 moles of S and 15 moles of F2?

Explanation:

1. Gather all the information in one place.

            S + 3F₂ ⟶ SF₆

n/mol:   6    15

They have given us the amounts of two reactants and asked us to calculate the amount of product. This is a limiting reactant problem.

2. Calculate the moles of SF₆ you can obtain from each reactant

From S:

From F₂:

SF₆ is the limiting reactant, because it gives fewer moles ( 5 mol) of SF₆.

The reaction can form 5 mol of SF₆.
