Unformatted text preview: 1) What is the theoretical yield (in g) of solid sodium oxide (molar mass: 38.99 g/mol) if 12.5 g of solid sodium (molar mass: 22.99 g/mol) was reacted with 9.57 g of O 2 (molar mass: 32.00 g/mol) gas? Report to one decimal place. 2) Consider the following unbalanced reaction equation: Al (s) + HF (g) AlF 3 (s) + H 2 (g) What is the percent yield of aluminum fluoride (molar mass: 83.98 g/mol) if 50.5 g of aluminum fluoride is produced when 30.0 g of aluminum (molar mass: 26.98 g/mol) is reacted with 50.0 g of hydrogen fluoride (molar mass: 20.008 g/mol). Report to one decimal place. Answers: 1. 10.2 g 2. 72.2%...
