To find molar mass of a compound, you add all the element's mass together. In this case we have C (carbon), H (hydrogen), Cl (chloride).
C = 12.01
H = 1.01
Cl = 35.45 x 3 = 106.35
Since there is a subscript of 3 for chlorine, we multiply chlorine's mass by 3.
We add all of them together.

The answer is 119.37g/mol CHCl3
