Question

how is stoichiometry used to calculate amount of product from amount of reactant?
a. the coefficients give the ratio of moles product to grams product.
b. the coefficients give the ratio of moles reactant to moles product.
c. the coefficients give the ratio of actual yield to theoretical yield.
d. the coefficients give the ratio of grams reactant to grams product.

Explanation:

Stoichiometry uses the coefficients in a balanced chemical equation. These coefficients represent the mole - to - mole ratio between reactants and products. This ratio is used to calculate the amount of product from the amount of reactant.

Answer:

B. The coefficients give the ratio of moles reactant to moles product.
