Question

A solution contains 410.3 g of h2so4 per litre of solution at 20

Answer 1

A liter of solution weights 1243g

It is told that 410.3 g of this is H2SO4 so the rest of the weight ( 1243 - 410 = 833 g ) must be water.

Molar mass H2SO4 = 98.078 g/mol

Moles H2SO4 = 410.3 g/ 98.078 = 4.183

m = moles solute / Kg solvent = 4.183 / 0.833 = 5.02

Answer 2

Answer:

5.02

Explanation:

molality=mass/kg
