Question

How can one tell how much of each reactant will be used in a reaction?

A. The coefficients tell the ratio of grams of reactants used in the reaction
B. The molar masses of the molecules tell how many moles of each reactant are used
C. The molar masses of the molecules tell how many grams of each reactant are used
D. The coefficients tell the ratio of moles of reactants used in the reaction

Answer 1

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

Step-by-step explanation:

The molar ratio is central to all stoichiometric calculations.

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

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

You must get over the "mole hill."
