Describe how molarity can be used in stoichiometry calculations

The stoichiometric coefficients in your balanced chemical equation can represent molecules or moles or molarity.

When you balance an equation, you can use the coefficients to determine the quantity of either products or reactants. If the reaction occurs in water, then you can either do the conversion from reactants to products using moles or molarity.

Explanation:

For example, if you have a 1.5M solution of H2SO4, then the concentration of SO4-2 in solution can be determined by the balanced dissociation equation H2SO4 = 2H+ + SO4-2.

1.5M H2SO4(1M SO4-2/1M H2SO4) = 1.5 M SO4-2
