Mole-Ratios+-+Mole-Mole+Conversions

 Mole-Ratios - Mole-Mole Conversions  What is a mole ratio? A conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles. Mole Ratios are used to convert between moles of reaction and moles of reactants or between moles of products in chemical calculations. Example:How many moles of Aluminum are needed to form 3.7 mol Al203 S1: mol Al S2: 3.7 mol Al2O3 S3: 4 mol Al=2 mol Al2O3 S4: 3.7 mol Al2O3 x 4 molo Al/ 2 mol Al2O3 =7.4 mol Al

Example: How many moles of ammonia are produced when 0.60 mol of nitrogen reacts with hydrogen? 0.60 mol N2 mol Nh3 0.60 mol N2 x 2 mol NH3/1 mol N2= 1.2 mol Nh3





Lab: When baking soda is an ingredient in your recipe, its purpose is to make the batter rise and produce a product with a light and fluffy texture. Thats because baking soda, or sodium hydrogen carbonate, decomposes upon heating to from carbon dioxide gas.
