Question

How is stoichiometry used to calculate amount of product from amount of reactant?

A. The coefficients give the ratio of actual yield to theoretical yield
B. The coefficients give the ratio grams reacted to grams product
C. The coefficients give the ratio moles product to the grams product.
D. The coefficients give the ratio of mole reactant to moles product.

Answer 1

D. The coefficients give the ratio of mole reactant to moles product.

Step-by-step explanation:

In stoichiometric calculations, the amount of product formed from reactants can be determined.

• Using this approach, the number of moles of reactants and products on both sides of the expression must be balanced.
• As a rule of thumb, the coefficients give the ratio of moles of reactants to moles of products.
• This is very useful in a number of calculations using the stoichiometric approach.
