Graphite is Allotrope of carbon and it is the purest form of carbon.
So, indirectly question says " calculate the mass of carbon that must be burnt to reduce 13.2g of CO₂ "

See the reaction :-
C + O₂ -------> CO₂
Here, 1 mole of CO₂ is formed by 1 mole of Carbon
or, 44g of CO₂ is formed by 12 g of Carbon
∴ 1 g of CO₂ is formed by 12/44 g of Carbon
∴ 13.2 g of CO₂ is formed by 12/44 × 13.2 = 3.6 g of carbon
Hence , mass of carbon = 3.6g

So, graphite mass = 3.6g

Hello Dear.

Here is the answer---

We know, Graphite is the Form of Carbon.

Thus, Gram Molecular mass of Graphite(Carbon) = 12 grams.

Gram Molecular mass of Carbon dioxide = 44 grams.
 
Given mass of Carbon dioxide = 13.2 grams


Reaction of the Above Conditions will be---

  C    +    O₂    ⇒----------------------------------⇒   CO₂

From the equations,

  ∵  44 grams of CO₂ is produced by the 12 grams of C.
∴ 1 grams--------------------------------------12/44 grams of C.
 ∴ 13.2 grams---------------------------------(12/44) × 13.2 grams of C.
                                                             = 3.6 grams of C.


Thus, Mass of Graphite(Carbon) required to produce the 13.2 grams of Carbon dioxide is 3.6 grams.
