When 24.9 grams of ethane (C2H6) react with excess oxygen to produce carbon dioxide, the percent yield is 56.8%. What was the actual yield of the reaction?
2C2H6 + 7O2 yields 4CO2 + 6H2O
20.7 g
41.5 g
62.2 g
64.3 g

Best ResponseYou've already chosen the best response.1First we need to find the theoretical yield, then multiply it by the yield percentage. So, you need to convert the mass to moles. Use: \(\sf moles=\dfrac{mass}{Molar~mass}\) Next we need a ratio of the moles of what you're using and what you're producing, and their respective stoichiometric coefficients from the balanced reaction (the numbers preceding the chemical formulas): \(\sf\dfrac{moles~of~ethane}{ethane's~coefficient}=\dfrac{moles~of~CO_2}{CO_2's~coefficient}\) Plug in moles of ethane and the coefficients and solve for moles of carbon dioxide. This is the theoretical yield, the MOST you could produce with what you have. Now multiply by 0.568. Done
