a solution of h2so4 (aq) with a molal concentration of 6.25 m has a density of 1.3 g/mL. what is the molar concentration of this solution?
6.25 m is 6.25 mol/kg solvent
6.25 mol H2SO4 = 6.25 x molar mass H2SO4 = about 610g but you need to do it more accurately.
So we have 610/(610g + 1000g)soln or
610/1610 g soln.
That 6.25 mol/1610 g soln. Use density to convert 1610g to L, then M = mols/L
