concentrated aqueous sulphuric acid is 98% H2SO4 (sulphuric acid ) by mass and has a density of 1.80gL-1 (gL raise to the power -1) . Volume of acid required to make one litre of 0.1 M H2SO4 is???
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
Density = 1.8 g/L
Volume of solution = Mass of solution/ Density
= 55.55 ml
= 0.055 L
M1V1 = M2V2
18.18 x V1 = 0.1 x1
V1 = 0.0055 L = 5.5 ml
Hence , volume of acid required = 5.5 ml
