WebClick here👆to get an answer to your question ️ Calculate the molality of 1 litre solution of 93% H2SO4 (weight / volume). The density of the solution is 1.84 g/ml . WebWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +.
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 WebIIT JEE 1990: Calculate the molality of 1.0 L solution of 93 % H2SO4, (weight/volume).
