what is the molar mass of chcl3?\n48.47 g/mol\n83.92 g/mol\n119.37 g/mol\n121.39 g/mol

Answer

Explanation:

Step1: Identify atomic masses

The atomic mass of C (carbon) is approximately 12.01 g/mol, H (hydrogen) is approximately 1.01 g/mol, and Cl (chlorine) is approximately 35.45 g/mol.

Step2: Calculate molar - mass of (CHCl_3)

In (CHCl_3), there is 1 C atom, 1 H atom, and 3 Cl atoms. The molar mass (M) is calculated as (M=(1\times12.01)+(1\times1.01)+(3\times35.45)). First, calculate the mass contribution of each element:

Mass of C: (1\times12.01 = 12.01) g/mol
Mass of H: (1\times1.01 = 1.01) g/mol
Mass of Cl: (3\times35.45=106.35) g/mol Then, sum them up: (M = 12.01+1.01 + 106.35=119.37) g/mol

Answer:

119.37 g/mol (corresponding to the third option)
