There are different substances present in an organic compound. If an organic compound contains different substances then there are some physical or chemical methods for the process of isolation, so that we will get different substances from the organic compound, which may or may not contain impurities.
To get rid of impurities after the isolation process purification process has to be done, so that we will get a purified substance from an organic compound.
Purification may be done using the method of sublimation, distillation and so on.
6.0m(mol/kg) of HCl 125mL H2O = 0.125kg 6mol/kg = n mol/0.125kg, n = 0.75mol When 0.75mol of HCl reacts, 0.75/2=0.375mol of H2 is produced. H2 = 2g/mol So, 0.375mol H2 = 0.75g
