Answer:
a. 4.45 g
Step-by-step explanation:
To calculate the mass of chlorine in 5 g of CHCl3, we need to first determine the molar mass of CHCl3 and the mass percentage of chlorine in CHCl3.
The molar mass of CHCl3 can be calculated as follows:
M(CHCl3) = M(C) + M(H) + M(Cl) x 3
= 12.01 g/mol + 1.01 g/mol + 35.45 g/mol x 3
= 119.38 g/mol
The mass percentage of chlorine in CHCl3 can be calculated as follows:
Mass of chlorine in CHCl3 = M(Cl) x 3 = 35.45 g/mol x 3 = 106.35 g/mol
Mass percentage of chlorine in CHCl3 = (106.35 g/mol / 119.38 g/mol) x 100% = 89.0%
Therefore, in 5 g of CHCl3, the mass of chlorine can be calculated as follows:
Mass of chlorine in 5 g of CHCl3 = 5 g x 89.0% = 4.45 g
Therefore, the mass of chlorine in 5 g of CHCl3 is 4.45 g.
