What volume of water is to be added to 100 cm^3 of 0.5M NaOH solution

1.	What volume of water is to be added to 100 cm^3 of 0.5M NaOH solution to make it 0.1 M solution?
Answer» `200cm^3` `400cm^3` `500cm^3` `100cm^3` Solution :`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`
