1. Stoichiometric Calculations Objectives: 6.0 Solve stoichiometric problems involving relationships among the number of particles, moles, and masses of reactants and products in a chemical reaction 6.3 Identifying the nomenclature of ionic compounds, binary compounds, and acids 6.4 Classifying chemical reactions as composition, decomposition, single replacement, or double replacement

2. Mole-to-Mole Conversions 2K(s) + 2H 2 O(l) → 2KOH(aq) + H 2 (g) What is the mole ratio of potassium (K) to hydrogen (H 2 )? How many moles of hydrogen will be produced in this reaction with 0.0400 moles of potassium? 0.0400 mol K x 1 mol H 2 /2 mol K = ????

3. Mole-to-Mass Conversions 1 step further: In the previous example, how many GRAMS of hydrogen will be produced? 0.0400 mol K x 1 mol H 2 /2 mol K x 2.0158 g H 2 /mol H 2 = ???

4. Mass-to-Mass Conversions And 1 more step: Using the same equation, if you have 73.8g of potassium, how may grams of hydrogen will be produced? 73.8g K x mol K/22.990g K x 1 mol H 2 /2 mol K x 2.0158g H 2 /mol H 2 = ???
