If 36 g of water are produced from two moles of C₃H₈O, the percent yield of the reaction is ________. 2 C₃H₈O + 9 O₂ → 6 CO₂ + 8 H₂O

From the balanced chemical equation, we can see that 2 moles of C₃H₈O produce 8 moles of H₂O. So, the theoretical yield of water is 8 moles or 144 g (since molar mass of H₂O is 18 g/mol). The actual yield is given as 36 g. Using the formula for percent yield: Percent yield = (actual yield/theoretical yield) x 100% Substituting the given values, we get: Percent yield = (36/144) x 100% = 25% Therefore, the correct answer is (C) 25%.
