Question

Calculate the number of moles of CO2 produced from the complete combustion of 2.5g of carbon
(C=12, O=16)

Answer 1

thus, on complete combustion 0.2083 moles of CO2 is produced.

Answer 2

Answer:

The number of moles of CO₂ produced  is equal to 0.2083 from the complete combustion of 2.5g of carbon.

Explanation:

The combustion reaction of carbon:

         $C(s)+O_{2}(g)$  →  $CO_{2}(g)$

One mole of carbon combined with one mole of oxygen and produced one mole of carbon dioxide. We can say that one mole of carbon produced one mole of CO₂.

12g of carbon will produce $=44g$ of CO₂

We have given 2,.5grams of carbon.

Therefore, 2.5g of carbon will produce CO₂ $=\frac{44}{12}*2.5$

                                                                        $=9.167g$ of CO₂

Now, 44g of carbon dioxide has moles $=1mole$

        9.165g of CO₂ has number of moles $=\frac{9.165}{44}=0.2083moles$
