Answer:
Therefore, the mass of chlorine in 35g of CCl4 is 32.17 grams.
Step-by-step explanation:
The molecular formula of CCl4 is carbon tetrachloride, which consists of one carbon atom and four chlorine atoms.
To calculate the mass of chlorine in 35g of CCl4, we need to first determine the molar mass of CCl4.
The molar mass of CCl4 = (1 x atomic mass of carbon) + (4 x atomic mass of chlorine)
= (1 x 12.01 g/mol) + (4 x 35.45 g/mol)
= 12.01 g/mol + 141.8 g/mol
= 153.81 g/mol
Next, we can use the molar mass to calculate the number of moles of CCl4 in 35g:
Number of moles of CCl4 = mass / molar mass
= 35 g / 153.81 g/mol
= 0.227 moles
Since there are four chlorine atoms in one molecule of CCl4, the number of moles of chlorine is:
Number of moles of chlorine = 4 x number of moles of CCl4
= 4 x 0.227 moles
= 0.908 moles
Finally, we can calculate the mass of chlorine in 35g of CCl4:
Mass of chlorine = number of moles of chlorine x atomic mass of chlorine
= 0.908 moles x 35.45 g/mol
= 32.17 g
Therefore, the mass of chlorine in 35g of CCl4 is 32.17 grams.
