The molality of H₂SO₄ solution is 24.2 m.
<u>Explanation:</u>
We need to find the molality of sulfuric acid.
Mass of sulfuric acid = 785.6 g
Mass of water = 359 g
We have to find the moles of H₂SO₄ by using its mass and molar mass as,
Moles of H₂SO₄ = 
= 8.7 moles
Mass of the solution in kg =
= 0.359 kg
Molality = 
= 
= 24.2 m
So molality of the H₂SO₄ solution is 24.2 m.

Explanation:
Why are all ionic compounds crystalline in structure?
Ionic compounds are generally hard, but brittle. ... The repulsive forces between like-charged ions cause the crystal to shatter. When an ionic crystal breaks, it tends to do so along smooth planes because of the regular arrangement of the ions.
When a non metal gains or share by two electrons then the valency will be 2^- or 2^+
