Question

an experiment only formed 14 g of product (actual yield), thus the percent yield of product for that experiment is 1.4/2.0x100 - 70% % yield actual yield theoretical Wald X 100 You can rearrange this equation to calculate the actual yield if given the % and theoretical yields, or the theoretical yield if given the % and actual yields. Let's Practice: 1. Answer the following questions based on the reaction below (5pts) 2 NaCl + Mg0 Na2O + MgCl2 What is the theoretical yield of sodium oxide (in grams) ir 24.0 grams of sodium chloride reacts with 10.5g of magnesium oxide? (1.25pts) reacts with coretical yield of so. Na2O + MgCl, b. If 10.5 g of Naz0 is formed during the reaction in part (a), what is the percent yield? (1.25pts) c. A student carried out the reaction in part (a) and got 92% yield of Na20. What is the student's actual yield? (1.25pts) d. What is the theoretical yield if the reaction above is 98.0% efficient and yields 15.4g! Na20 when 10.0 g of Mgo completely reacts with an excess of NaCl? (1.25pts)
