What is the molar mass of CHCl_3?

• A. 119.37 g/mol
• B. 83.92 g/mol
• C. 121.39 g/mol
• D. 48.47 g/mol

Answer: (A)

Verified step by step guidance

1. Identify the elements present in the compound CHCl_3, which are Carbon (C), Hydrogen (H), and Chlorine (Cl).
2. Determine the number of atoms of each element in one molecule of CHCl_3: 1 Carbon, 1 Hydrogen, and 3 Chlorine atoms.
3. Find the atomic masses of each element from the periodic table: Carbon (approximately 12.01 g/mol), Hydrogen (approximately 1.008 g/mol), and Chlorine (approximately 35.45 g/mol).
4. Calculate the total mass contributed by each element by multiplying the atomic mass by the number of atoms: for Carbon, \$1 \times 12.01\(; for Hydrogen, \)1 \times 1.008\(; for Chlorine, \)3 \times 35.45$.
5. Add the masses of all elements together to find the molar mass of CHCl_3: \$12.01 + 1.008 + (3 \times 35.45)$.
