To calculate molarity :-98×1000/98×100=10M.
To calculate normality :- molarity ×n- factor
n- factor for h2so4 is 2.
N=10×2=20N.

Molarity m is defined as the number of solute per 1000g of solvent I.e . molarity =moles of solute/ kilograms of solvent 2% by mass >H2SO4 =2\100×98\198=1.96g.H2SO4 is dissolved in 1000g (H2)the amount of solute must be given in moles and the amount of solvent in kilograms 1.96g H2SO4=1.96/198=0.02moles H2SO4 molarity =0.02/1kgH2O=0.02m
