The molality of H₂SO₄ solution is 24.2 m.
Explanation:
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 = [tex]$\frac{785.6g}{90.08 g/mol}[/tex]
= 8.7 moles
Mass of the solution in kg =[tex]$\frac{359}{1000}[/tex] = 0.359 kg
Molality = [tex]$\frac{moles}{solvent (kg)}[/tex]
= [tex]$\frac{8.7 mol }{0.359 kg}\\[/tex]
= 24.2 m
So molality of the H₂SO₄ solution is 24.2 m.
