6. You'll use a stoichiometry calculation to predict the mass of aspirin you should obtain if all of the salicylic acid is converted to product. Since you'll do that calculation in today's lab, you'll use a different reaction to demonstrate that you can work stoichiometry problems unassisted: the condensation of ethanoic acid and cyclohexanol (in Question 1). Determine the mass of the ester product that should form when 2.23 grams of ethanoic acid is completely converted to ester with an excess of cyclohexanol. Show all three steps of the stoichiometry calculation (with units), and express your answer with units and the appropriate number of significant figures. ethanoic acid + cyclohexanol → ester product + water 60.05 g/mole 100.16 g/mole 142.19 g/mole

[Tutorial: Limiting reactant stoichiometry] This question will walk you through the steps of calculating the mass of products produced based on your determination of the limiting reactant.   b) Step 2a: Use dimensional analysis to determine the theoretical yield of the product. Calculate the theoretical yield in grams Al₂O₃ from the complete reaction of 64.7 grams Al according to the following balanced chemical equation: 2 Al(s) + Fe₂O₃(s) → Al₂O₃(s) + 2 Fe(s) c) Calculate the theoretical yield in grams Al₂O₃ from the complete reaction of 201 grams Fe₂O₃ according to the following balanced chemical equation: 2 Al(s) + Fe₂O₃(s) → Al₂O₃(s) + 2 Fe(s) d) Which of the following substances is the limiting reactant? e) What is the mass in grams of the excess Fe₂O₃ remaining after the partial reaction of 201 g Fe₂O₃ with 64.7 g Al? Give your answer to three significant figures.

41 SAM Pearson Learning: Ch 03R: Chemical Reactions and Chemical Quantities QUESTION Stoichiometry is a term chemists use to describe calculations that determine the relative quantities of reactants or products involved in a chemical reaction. Using stoichiometry, chemists can determine the amount of product that can be formed during a chemical reaction from a given amount of reactant. Chemists can also determine the amount of reactant needed to produce a desired amount of product using the same process. Select the missing conversion factor for the following set of calculations. Assume 12.3 grams of nitrogen dioxide, NO,, react with excess water. The problem requires that you determine the mass of nitric acid, HNO, formed from this reaction. 3 NO,(9) + H̟O(1) –→ 2 HNO,(aq) + NO(9) 2 m ol HNO, 63.02 g HNO, 3 mol NO, 12.3 g NO,x. 1mol HNO, := 11.2 g HNO, supnort
