The molar mass for chloroform, represented by the chemical formula CHCl3, is 119.37 grams per mole. The molar mass is calculated by the atomic weight per mole.
The atomic mass of carbon is 12.01 grams per mole. The atomic mass of hydrogen, represented by the chemical symbol "H," is 1 gram per mole. The atomic mass of chlorine, represented by the symbol "Cl," is 35.45 gram per mole, so the total mass of chlorine atoms in chloroform is 35.45 times three. About 89.09 percent of the molar mass of chloroform comes from the three chlorine atoms, while 0.84 percent comes from the hydrogen atom.
