In lab, a student weighed out 1.609 g of unknown in a beaker. The student added 67 mL DI water and followed the protocol in the lab to filter and dry the product, which had a final mass of 0.697 g. The filtrate was tested, and the student determined that Na3PO4 was the limiting reactant. Determine the percent by mass composition of Na3PO4 in the original unknown sample.

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".
