What volume of water is to be added to 100 `cm^3` of 0.5 M NaOH solution to make it 0.1 M solution ?

A

`200cm^(3)`

B

`400cm^(3)`

C

`500cm^3`

D

`100 cm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`M_1V_1=M_2V_2`
`0.5 xx100= 0.1 xx V_2`
`V_2 = 500 cm^3`
Volume of water to be added to 100 `cm^3` of solution
=500 - 100 = 400 `cm^3`
