Stoichiometry

Stoichiometry Stoichiometry Stoichiometry is the process of using an equation to determine the exact amount of chemicals given off in a reaction.

Moles of A Moles of B Grams of A Grams of B Moles of A = Moles of B Use the balanced equation Molar mass A = 1 mole of A Use the periodic table Moles of A Moles of B Grams of A Grams of B Molar mass B = 1 mole of B

Practice Problem One How many grams Li2 will be produced from 12g of bismuth dilithide? BiLi3  Bi2 + Li2

Practice Problem Two How many grams of fluorine gas (F2) are needed to produce 25g of FCl? F2 + Cl  FCl

Practice Problem Three How many grams of sodium are needed to completely react with 75g of Sb2? Na + Sb2  Na3Sb
