<em>Paper chromatography is especially useful in characterizing amino acids. The different amino acids move at differing rates on the paper because of differences in their R groups.</em>
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
