Calculate the mass of chloroform that contains 1.00x10^12 molecules of chloroform

Molar mass of chloroform (CHCl3)
C = 1 * 12 = 12 a.m.u
H = 1 * 1 = 1 a.m.u
Cl = 3 * 35.5 = 106.5 a.m.u
 Molar Mass (CHCl3) = 12 + 1 + 106.5 = 119.5 g / mol
 
Knowing that: The value of Avogadro's constant corresponds to approximately  molecules, if chloroform contains  molecules.  
We have:
 

 
Now, how many grams are there in the chloroform molecule?
