What is the percent yield if 185 grams of SiO₂ are made from 328 g of Cr₂O₃ by the following equation? 3 Si(s) + 2 Cr₂O₃(s) → 3 SiO₂(s) + 4 Cr(l)

Question

Quizplus · Accepted Answer

The theoretical yield of SiO2 can be calculated using stoichiometry. The molar mass of Cr2O3 is 152 g/mol, and the molar mass of SiO2 is 60 g/mol. From the balanced equation, 2 moles of Cr2O3 produce 3 moles of SiO2. Therefore, 328 g of Cr2O3 (2.16 moles) can theoretically produce 3.24 moles of SiO2, which is 194.4 g. The percent yield is (185 g / 194.4 g) * 100% = 95%.
