Combustion And Flame

Step 1: Determine the amount of carbon in CO :
When the compound undergoes complete combustion, carbon from the compound reacts with oxygen to produce CO . The molar mass of CO is: The molar mass of carbon (C) is 12 g/mol. In 44 g of CO , 12 g is carbon. Therefore, the mass of carbon in 220 mg of CO can be calculated as:
Step 2: Calculate the percentage of carbon in the compound:
The mass of carbon in the original organic compound is 60 mg. The total mass of the compound is 500 mg. The percentage of carbon in the compound is given by:
