The density of HCL is 1.19 g/ml which means 1.19 Kg/L
The solution is 38%, so the actual HCL conc. will be 1.19 x 38/100 = 0.4522 Kg And after conversion, the answer will be 452 gms/Litre.
However, the molar mass of HCL is 36.5 g/mol
Thus, our final answer will be 452g/36.5 which is now 12.38 mol/lire.
