3.38 For many years chloroform (chcl3 calculate the percent composition by mass of this compound
Accepted Answer
To calculate the percent composition by mass of chloroform (CHCl3), follow these steps:
1. Find the molar mass of each element:
Carbon (C): 12.01 g/mol
Hydrogen (H): 1.01 g/mol
Chlorine (Cl): 35.45 g/mol
2. Calculate the molar mass of chloroform:
CHCl3 = 12.01 + 1.01 + (35.45
3) = 119.38 g/mol
3. Calculate the percent composition of each element:
% C = (12.01 g/mol / 119.38 g/mol)
100% = 10.06%
% H = (1.01 g/mol / 119.38 g/mol)
100% = 0.85%
% Cl = (35.45 g/mol
3 / 119.38 g/mol)
100% = 89.09%
Therefore, the percent composition by mass of chloroform is approximately:
Carbon (C): 10.06%
Hydrogen (H): 0.85%
Chlorine (Cl): 89.09%
