A solution of H2SO4 with a modal concentration 6.25m has a density of 1.300 g/ml. What is the molar concentration?
Do you mean molal concn of 6.25m?
6.25 m means 6 .25 moles/1000g solvent.
grams solute = 6.25*40 = 250 grams.
Total mass of solute + solvent = 1000 + 250 = 1250 grams soln.
volume = mass/density = 1250g/1.30 = ??
M = moles/L soln.
The boiling point of an aq solution 102.11 C. What is the freezing point?
