Please answer ALL questions, not just 1. Specifically in need for 3-8. 1. Determine the formula weight for each compound: sulfur tetrafluoride, carbon dioxide, sodium chloride, phosphorus pentafluoride, calcium phosphate, water, propane (C3H8), iron(III) sulfate. Which compounds would also have a molecular weight or molar mass? What is the difference between a formula weight and a molecular weight? 2. Determine the percent composition for each compound in question 1. Is it possible for two compounds to have the same percent...
