Combustion equations are used to find empirical formulas. This can also be referred to as elemental analysis. Here is how we can get the percentage:
First, calculate the molar mass of CO2
The molar mass of CO2= (12+16x2) =44
Atomic mass of carbon is 12
Calculate weight of carbon in the 4.4g CO2;
= 12/44 x 4.4 =1.2 grams
that means the mass of carbon in the compound was 1.2 grams
Calculate the % mass of C in the compound of total weight 1.6g
= 1.2/1.6 x 100= 75 %There % of carbon in the compound = 75%
