98% by weight means 98 gm H2SO4 in 100 gm solution or 98 g H2SO4 in 2 g water.Number of moles of H2SO4 = 98/98 = 1Density = 1.8 g/LVolume of solution = Mass of solution/ Density = 100/1.8 = 55.55 ml = 0.055 L Applying,M1V1 = M2V218.18 x V1 = 0.1 x1V1 = 0.0055 L = 5.5 ml Hence , volume of acid required = 5.5 ml
