Question

contains. Calc. the concentration if 200. me of solution 15.ome of any soluble liquid solute. contains 7.50g w Calc. the (*) % concentration of 150 ml solution Of dissolved SOUD NA2SO4

Answer 1

10 )

Given

Volume of solute : 15.0 ml

Volume of solution : 200 ml

We know that , volume percent = [ Volume of solute / volume of solution ] 100

$\therefore$ volume percent = [ 15.0 ml / 200 ml ] 100

volume percent = 7.5

11 )

Given

Mass of Na₂SO₄ = 7.50 g

Volume of solution = 150 ml

We know that , Mass / volume Percent = [ Mass of solute / volume of solution ] 100

Mass / volume Percent = [ 7.50 / 150 ] 100

Mass / volume Percent = 5

ANSWER : W/V % of Na₂SO₄ solution = 5
