1. Mass-Mole conversions using Mole-to-Mole Ratios Or Math Math Math….

2.  Equations must be balanced  Start every problem with the Balanced equation at the top and fill in moles and grams below  Mole to Mole conversion short-cut: Divide the amount of moles by the coefficient above it and then multiple it by the coefficient of the moles you are calculating. Reminders

3. 1.Write the balance equation 2.Fill in the information you know (mol, g, and circle the answer(s) you are looking for). 3.Use calculations/railroad method/short cuts to move through the equation to get to the answers a.Mole to Mole: Use the ratios in the balanced equation. b.Mole to gram: Use the molar masses from the periodic table. Steps to Mass-mole conversions

4.  AgNO 3 + NiCl 2  AgCl + Ni(NO 3 ) 2 1.If you have 32.9 g of nickel (II) chloride and excess silver nitrate, how many moles of silver chloride will be formed? 2.If you have 8.12 grams of silver nitrate and excess nickel (II) chloride, how many grams of silver chloride will be formed? 3.If 234.8g of Nickel (II) nitrate are formed in a reaction, how many grams of each reactant was used?
