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

A

`200cm^3`

B

`400cm^3`

C

`500cm^3`

D

`100cm^3`

Text Solution

Verified by Experts

`M_1V_1=M_2V_2`
`0.5xx100=0.1xxV_2 rArr V_2=500cm^3`
Volume of water to be added to 100 `cm^3` of solution
= `500-100=400cm^3`
