What is the molar mass of CHCl3?<br> 48.47 g/mol<br> 83.92 g/mol<br> 119.37 g/mol<br> 121.39 g/mol
kolbaska11 [484]

119.37 g/mol

<h3>Further explanation</h3>

Relative atomic mass (Ar) and relative molecular mass / molar mass (M)  

the molar mass/molecular mass of a compound : the sum of the relative atomic mass (Ar) of the constituent atoms

M AxBy = (x.Ar A + y. Ar B)  

Atomic weight (Ar) of :

  • C : 12.0107 g/mol  
  • H : 1.00784 g/mol  
  • Cl : 35.453 g/mol  

The molar mass of CHCl₃

\tt CHCl_3=12.0107+1,00784+(35,453\times 3)=119.37~g/mol
