How many moles of carbon dioxide, CO2, are produced when 4.50 moles of propane, C3H8, react?

Moles of Carbon dioxide : 13.5

Given

4.5 moles propane

Required

moles of Carbon dioxide

Solution

Reaction(Combustion of Propane) :

C₃H₈(g)+5O₂(g)→3CO₂(g)+4H₂O(g)

In a chemical equation, the reaction coefficient shows the mole ratio of the reacting compounds (either in reactants or products)

From the equation, mol ratio of Propane(C₃H₈) : Carbon dioxide(CO₂) : 1 : 3, so mol CO₂ :

= 3/1 x mol Propane

= 3 x 4.5 moles

= 13.5 moles

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

catya your not at all which answer i've seen you do this on another question!
