Molar Masses

Question 10 • LA-Chemistry A

What is the molar mass of CHCl3?

Answer
A
48.47 g/mol
B
83.92 g/mol
C
119.37 g/mol
D
121.39 g/mol

Explanation

Add the atomic masses for each atom in CHCl₃: carbon contributes 12.01 g/mol, hydrogen contributes 1.008 g/mol, and three chlorine atoms contribute 3 × 35.45 = 106.35 g/mol. The total is 12.01 + 1.008 + 106.35 = 119.368 g/mol, which rounds to 119.37 g/mol. Therefore, the molar mass is 119.37 g/mol.
