A sample of chloroform is found to contain 12.0 g of carbon, 106.4 g of chlorine, and 1.01 g of hydrogen. If a second sample of chloroform is found to contain 30.0 g of carbon, what is the total mass of chloroform in the second sample?

Respuesta :

Given:

Sample 1:

Chloroform is [tex]CHCl_{3}[/tex]

12 g Carbon

1.01 g Hydrogen

106.4 g Cl

Sample 2:

30.0 g of Carbon

Solution:

mass of chloroform from sample 1:

12 + 1.01 +106.4 =119.41 g

Now, for the total mass of chloroform in sample 2:

mass of chloroform [tex]\times[/tex][tex]\frac{given mass of carbon}{mass of carbon atom}[/tex]

mass of chloroform = 119.41 [tex]\times[/tex][tex]\frac{30}{12}[/tex] = 298.53 g
