Equivalent weight:
The equivalent weight of H2SO4 is:
98.0734 grams (molecular wt.)/ 2H+ ions = 49 grams/equivalent
This means 49 grams of H2SO4 is equivalent to one equivalent of H2SO4. If there is a one liter solution which contains 78.32 grams H2SO4, a number of equivalents are:
78.32 grams H2SO4/1× 1 equivalent/ 49 grams H2SO4 =1.6 equivalents
Because normality is equivalent to the number of equivalents per liter, a normality of this solution is 1.6 equivalents/liter, or 1.6 N.
