Model 4: Using Moles of Limiting Reagent in Stoichiometry The above pictures are not realistic because they involve so very few molecules. In a "real-world" sample, you are likely to have on the order of 10 molecules. Consider the following: Suppose you have a reaction vessel initially containing 13.5 moles of sulfur dioxide and 11.2 moles of oxygen mol SO, required to react with all O2 = 11.2 mol O2 x 2 mol SO 22.4 mol SO, 1 mol O2...

POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...
