Question

density of 2M solution of h2so4 is 1.08 g/ml what is molality of the solution​

Answer 1

Answer:

density of H₂SO₄ = 1.08 g/ml

Now , Molarity = Mole of H₂SO₄ / Litre of solution = 2M

 means , 2 mole in 1L solution

Mass of H₂SO₄ = 2 * 98 g = 196g

Mass of solution = 1.08 * 1000 = 1080 g

Mass of solvent = 1080-196 = 804 g = 0.8 kg

Molality = moles of H₂SO₄ / mass of solvent in kg = 2/0.8 = 2.5 m (Ans.)
