What is the theoretical yield in grams of Ca(OH)2 if 2.04 g of KOH reacts with 3.02 g of CaCl2x2H2O as shown by the below equation? (Use correct number of significant figures) CaCl2(aq) + 2KOH(aq) yields Ca(OH)2(s) + 2KCl(aq) In the part of the calculation that converts the number of grams to moles for CaCl2x2H2O, the two water molecules must be included in the molar mass needed to convert grams to moles (molar mass of CaCl2x2H2O is 147.0 g/mol). What is the limiting reactant?
1. What is the theoretical yield in grams of Ca(OH)2 if 2.04 g of KOH reacts with 3.02 g of CaCl2x2H2O as shown by the below equation? (Use correct number of significant figures)
CaCl2(aq) + 2KOH(aq) yields Ca(OH)2(s) + 2KCl(aq)
In the part of the calculation that converts the number of grams to moles for CaCl2x2H2O, the two water molecules must be included in the molar mass needed to convert grams to moles (molar mass of CaCl2x2H2O is 147.0 g/mol). What is the limiting reactant?
2. You carry out the sunthesis of Ca(OH)2 using the 2.04 g of KOH and 3.02 g of CaCl2x2H2O as in problem #1, and your yield of dry Ca(OH)2 is 1.22 g. What is the percent yield for the reaction? (Use the correct number of significant figures)
