How to figure out the normality/equivalent weight/equivalents of chemicals in a balanced equation (assuming necessary data given)

Normality= molarityxequivalent

Eg: H2SO4 + Na2OH ⇒ Na2SO4 + 2H2O

H2SO4 can neutralize 2 M of NaOH so equivalent of H2SO4 is 2 and that of NaOH is 1

For ions, equivalent is the number of charge and for acids or bases it is the acidity or basicity. 

Equivalent weight is weight of 1 equivalent of any compound

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

It has to be b i hope this
