WebA sulfuric acid solution containing 571.4 g of H2SO4 per liter of solution has a density of 1.329 g/cm3. Calculate the molality of H2SO4 in this solution A solution of H2SO4 with a molal concentration of 8.010 m has a density of 1.354 g/mL. What is the molar concentration of this solution? WebMass % of H2SO4 (w/v) = 93 % i.e. mass of solute H2SO4 in 100 mL = 93 g So mass of H2SO4 in 1 L (1000 mL)= 930 g Thus mass of solvent = mass of solution - mass of solute = 1840 - 930 g = 910 g = 0.910 kg Hence Molality = mass of solutemolar mass of solute × mass of solvent in kg = 93098 × 0.910 = 10.43 m
WebMolality shows how many moles are dissolved in every 1000 grams of solvent. m = Molality n = number of moles of solute p = solvent mass (grams) Given. mass H₂SO₄ = 571.4 g = 0.5714 kg. density = 1.329 g/cm³ = 1.329 kg/L.
