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

Options

A. `500 cm^(3)`
B. `450 cm^(3)`
C. `400 cm^(3)`
D. `100 cm^(3)`

Answer

B

Explanation

Before dilution equiv 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)`
