D. The coefficients tell the ratio of moles of reactants used in the reaction

Explanation:

The molar ratio is central to all stoichiometric calculations.

To get the mass of Compound B that reacts with compound A, you must

Convert the mass of A to moles Use the molar ratio from the balanced equation to find the moles of B Convert moles of B to grams.

You must get over the "mole hill."
