Phosphoric acid, a mild acid used among other things as a rust inhibitor, food additive, and etching agent for cavity repair by dentists, can be made from elemental phosphorus in a two-step process. In the first step, phosphorus and oxygen react to form diphosphorus pentoxide: P4(s)+  5O2(g)→  2P2O5(g) In the second step, diphosphorus pentoxide and water react to form phosphoric acid H3PO4:   P2O5(g)+  3H2O(l)→  2H3PO4(l) Suppose the yield of the first step is 97.%  and the yield of the second step is 92.%. Calculate the mass of phosphorus required to make 7.0kg of phosphoric acid. Be sure your answer has a unit symbol, if needed, and is rounded to  2 significant digits.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
