Question

Give the percent yield when 15.9 g of CO2 are formed from the reaction of 4.000 moles of C8H18 with 4.000 moles of O2.

2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O

Answer 1

1. Determine the limiting reagent.
2. Convert the limiting reagent to grams.
3. %yield = (15.9/g limiting reagent)*100 = ??
