Question

What is the molar mass of CHCl3?
48.47 g/mol
83.92 g/mol
119.37 g/mol
121.39 g/mol

Answer 1

119.37 g/mol

Further explanation

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

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