Challenge Problems
Push your limits with challenges.
Question 1
In a reaction where 3.0 moles of A and 5.0 moles of B produce a product C according to the equation A + 2B → C, identify the limiting reagent and calculate the theoretical yield of C if the molar mass of C is 50 g/mol.
💡 Hint: Draw a conversion chart if needed to visualize and calculate.
Question 2
Calculate the percent yield if 100 g of A produces 85 g of C in the reaction A → C.
💡 Hint: Setup yields and calculate first.
