zinc + sodium hydroxide + water →    sodium zinc hydroxide + hydrogen gas   If 180.20 grams of sodium hydroxide are reacted with 5.0 × 1022 particles of water, how many moles of hydrogen gas will be produced if the reaction proceeds with an 82.749% yield?   **I already know how to balance the equation. I need help calculating the percent yield with “x” product. Do I find the limiting reagent first and then multiply that by the given % yield?**

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".
