A solution was prepared by dissolving 43.6 g of H2SO4 in enough water to give 500.0 mL of solution at 22oC. Assume that the density of the solution at 22oC is 1.03 g/mL.
(a) What is mass percent (%w/w) of H2SO4 in this solution?
(b) Would the mass percent (%w/w) of H2SO4 change with changes in temperature? Explain.
(c) Is the mass-volume percent (%w/v) of a solution temperature dependent? Explain
