How many tons of carbon dioxide are equivalent to one ton of carbon?

You must determine how many grams are in a tonne. You then must then use the molecular weight of carbon to determine the moles of carbon in that many grams (i.e. (grams C)/(M.W. of C)). As there is one mole of Carbon in each mole of carbon dioxide, then multiply the resulting moles of carbon by the molecular weight of CO2 and you will have your answer.


One metric ton (tonne) of of carbon is equivalent to approximately 3.66 metric tons (tonnes) of carbon dioxide.
