3.38 For many years chloroform (chcl3 calculate the percent composition by mass of this compound hyrdogen is 1.008 solve it property

Accepted Answer

To calculate the percent composition by mass of chloroform (CHCl3), follow these steps:
1. Find the molar mass of chloroform:
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.008 g/mol
- Chlorine (Cl): 35.45 g/mol
- Molar mass of CHCl3 = 12.01 + 1.008 + (35.45
3) = 119.37 g/mol
2. Calculate the mass of each element in one mole of chloroform:
- Carbon: (12.01 g/mol / 119.37 g/mol)
100% = 10.06%
- Hydrogen: (1.008 g/mol / 119.37 g/mol)
100% = 0.84%
- Chlorine: (3
35.45 g/mol / 119.37 g/mol)
100% = 89.09%
Therefore, the percent composition by mass of chloroform is:
- Carbon: 10.06%
- Hydrogen: 0.84%
- Chlorine: 89.09%
