molarity of H2So4 solution is 18 moles if density of solution is 1.8 g/cm calculate the molality of solution

molarity of H2So4 solution is 18 moles if density of solution is 1.8 g

1.	molarity of H2So4 solution is 18 moles if density of solution is 1.8 g/cm calculate the molality of solution
Answer» Molality = mol H2SO4/kg solvent molarity = mol H2SO4/L solution Using DENSITY, MASS of the solution = 1.8g/ml * 1000 ml = 1800g Molecular weight of H2SO4 = 98g Mass of SOLUTE (H2SO4) = 18 mol * 98 G = 1764 g Mass of solvent = mass of solution - mass of solute = 1800 g - 1764 g = 36 g = 0.0036 kg Molality = mol. H2SO4/ kg of solvent = 18 mol/0.0036kg = 500 mol/kg
