for Solving a Reactant Using a Chemical Equation
Write a balanced chemical equation for the reaction
The mole ratio of any two compounds in a chemical reaction is given by the ratio of the
stoichiometric coefficients of those compounds in the balanced chemical equation.
Use this plan to answer the question:
1.
Convert of grams (1st molecule) consumed to moles using the molar mass of
phosphoric acid
2.
Calculate moles of (2nd molecule) consumed from moles of (1st molecule)
consumed using the mole ratio
3.
Convert moles of (2nd molecule) consumed to grams using the molar mass of
(2nd molecule)
