Respuesta :

mass percent of carbon (c) in CCl₄ = mass of C/mass of CCl₄
                                                        = 12 x 100/153.8 = 7.8%


Answer: The mass percent of carbon in carbon tetrachloride is 7.8 %.

Explanation:

In [tex]CCl_4[/tex], there are 1 carbon atoms and 4 chlorine atoms.

To calculate the mass percent of element in a given compound, we use the formula:

[tex]\text{Mass percent of carbon}=\frac{\text{Mass of carbon}}{\text{Molar mass of carbon tetrachloride}}\times 100[/tex]

Mass of carbon = 12 g

Mass of carbon tetrachloride = 153.8 g

Putting values in above equation, we get:

[tex]\text{Mass percent of carbon}=\frac{12}{153.8}\times 100=7.80\%[/tex]

Hence, the mass percent of carbon in carbon tetrachloride is 7.8 %.
