A solution is 0.25% by mass. The weight of solvent containing 1.25g. Of solutes would be

Answer»

506g
498.75 G
580.25 g
581.25 g

Solution :MASS of solution =100 g. Mass of solute = 0.25 g.
:. Mass of SOLVENT =100-0.25 = 99.75 g.
0.25 of solute is PRESENT in 99.75g of solvent
:. 1.25 g. of solute will be present in
`(99.75 xx 1.25)/0.25 =498.75` g of solvent.
