Question

Calculate the yield of CO2 on combustion of propane (based on – propane + O2 gives CO2 and water), starting with 5g of propane and 3g of O2

What is the actual and theoretical yield?

Answer 1

Hello, Abel,

Thanks for updating your question with an answer to the theoretical yield. I decided to try it myself and got 2.48 grams CO₂. With sig figs, 2,5 is correct. Oxygen is a limiting reagent. Good job.

To calculate actual yield, there needs to be a value for grams CO₂ actually obtained. Divide the actual by the theoretical masses and use that fraction for the percent yield.

Thanks again for your updated calculation,

Bob
