0.5 g of an organic compound (X) with 60% carbon will produce ______

\times 1 0^{- 1}

g of

CO X_{2}

on complete combustion.

Answer: 11

The percentage of carbon in an organic compound is related to the mass of

CO X_{2}

produced by:

Percentage of C = \frac{12}{44} \times \frac{mass of CO X _{2}}{mass of compound} \times 100

Given: 60% carbon, 0.5 g compound. Substituting:

60 = \frac{12}{44} \times \frac{mass of CO X _{2}}{0.5} \times 100

Solving for mass of

CO X_{2}

mass of CO X_{2} = \frac{60 \times 44 \times 0.5}{12 \times 100} = 1.1 g = 11 \times 1 0^{- 1} g

Therefore, the answer is 11.
