A solution of H2SO4(aq) with a molal concentration of 6.25 m has a density of 1.300 g/mL. What is the molar concentration of this solution?
Didn't I work this for you a couple days ago? 6.25m means 6.25 mols/kg solvent.
6.25 mol H2SO4 = 6.25 x molar mass = ? grams H2SO4.
Then solvent = 1000, H2SO4 = ? grams = total mass solution. Use density to convert to mL, convert to L and M = mols/L soln. Post your work if you get stuck.
