University of Louisville Chem 201-03 Dr. Hoyt Fall 2007 Stoichiometry basics–Chapter 3. Step 1. Write and balance the equation. Everything starts with the balanced equation! Step 2. Convert the given unit of the given species A (reactant or product) to moles. (Could be given grams, or volume of a solution of known molarity, or P, V and T of a gas, or whatever–convert to moles.) Step 3. Convert these moles of the given species A (reactant or product) to the moles of the desired species B (reactant or product) using the reaction ratio. The reaction ratio comes from the balanced equation.

Unformatted text preview: This is why you need step 1. Step 4. Convert the moles of the desired species to the desired units. Overall strategy: do whatever you need to do to get to Step 3, Moles A –> Moles B. Everything else is details. Moles A –> Moles B is the guts of the problem. Example The reaction of titanium(IV) chloride with water produces titanium(IV) oxide and hydrogen chloride. How many grams of titanium(IV) chloride are needed to make 325 g of titanium(IV) oxide? (Titanium is Ti.)...
