Solution:
In 100 gm of HCl solution, we would have 37 gm of pure HCl.
Hence the volume of HCl present would be equal to:
\frac{37}{1.2}=30.83 ml
Thus, 30.83 ml of HCl would have 37 gm of pure Hcl.
Hence in 10 ml of HCl, we would have 12 gm of pure HCl.
So, the mass of anhydrous HCl would be equal to: 32.4 gm.
