You have 59.736 mol of CO2, convert moles of CO2 produced by propane to moles of coal

Question

balanced chemical equation for the combustion of propane:

 

2C₃H₈ + 10O₂--> 6CO₂ + 8H₂O

 

Grams of propane converted to moles of propane = 199.12 moles propane

 

Moles of propane converted to moles of CO2 =  597.36 mol CO2

 

Convert moles of Co2 produced by propane to moles of coal.

Answer 1

What is this question asking? You are given moles of CO₂ and then why are you converting moles of propane to moles of CO2 and getting 597.36?

 

2C₃H₈ + 10 O₂--> 6CO₂ + 8H₂O

To find moles of propane needed to produce 59.736 moles of CO₂:

59.736 moles CO₂ x 2 moles C₃H₈/6 moles CO₂ = 19.912 moles propane

To find moles of coal that generates generates this same amount of CO₂:

59.736 moles CO₂ x 1 mole C/mole CO₂ = 59.736 moles of C (coal).
