On complete combustion, $0.492\, g$ of an organic compound gave $0.792 \,g$ of $CO _2$ The $\%$ of carbon in the organic compound is(Nearest integer)
On complete combustion, $0.492\, g$ of an organic compound gave $0.792 \,g$ of $CO _2$ The $\%$ of carbon in the organic compound is(Nearest integer)
Show Hint
Correct Answer: 44
Approach Solution - 1
weight of in
of in compound
Approach Solution -2
\[ \frac{12}{44} \times 0.792 = 0.216 \]
This calculation represents the mass of carbon in a given compound based on its molar mass and the amount of substance (0.792). The mass of carbon is found by multiplying the fraction of carbon atoms with the total mass.
\[ \% \, \text{of C in compound} = \frac{0.216}{0.492} \times 100 = 43.90 \% \]
This step determines the percentage of carbon in the compound by dividing the mass of carbon by the total mass of the compound and multiplying by 100. The result shows that the compound contains 43.90% carbon by mass.

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
