Question

How many moles of Propane are required to produce 22g of CO2 after Combustion


Please Guys answer this question with complete explanation ... Tomorrow is my exams I will highly grateful to you​

Answer 1

0.5 mole CH4 for 0.5 mole Co2 which is 22 gms. 44g of CO2 is required to produce 1g of methane. From the equation it is evident 44g co2 produced from 1 mol methane. So 22g CO2 is produced from 1/2 mol methane

Answer 2

Explanation:

CH

4

+O

2

⟶CO

2

+2H

2

O

Gram molecular mass of CO2 = 12 +2(16) = 44g/mol

From the reaction it is clear that 1 mole of methane on complete combustion produces 44g (1 mole) of carbon dioxide.

Therefore moles of CH

required to produce 22g of CO

are:
