What is the molecular weight of chloroform if 0.0275 mol weighs 3.28 g?

1 Answer

Nov 9, 2016

$"Moles of substance"$ $=$ $"Mass of substance"/"Molecular mass"$

Explanation:

So, rearranging that expression:

$"Molecular mass"$ $=$ $"Mass of substance"/"Moles of substance"$

$=$ $(3.28*g)/(0.0275*mol)$ $~=$ $120*g*mol^-1$ .

Is this consistent with the actual molecular mass?
