The volume of water of be added to 50 cm^(3) of a decimolar solution to convert it to a centimolar solution will be

Answer»

`500 cm^(3)`
`450 cm^(3)`
`400 cm^(3)`
`100 cm^(3)`

SOLUTION :Before dilutionequiv After dilution
`M_(1) V_(1) = M_(2) V_(2)`
`0.1 xx 50 = 0.01 xx V_(2)`
`:. V_(2)=500 cm^(3)`
:. Volume of water ADDED `=500-50=450 cm^(3)`
