40mg AgNO3 per ml means 80mg AgNO3 per 2 ml.
16 mg AgNO3 per ml means 80mg AgNO3 per 5 ml.
Hence we need to add 3 ml of water with every 2ml of solution
To what extent must a given solution containing 40mg AgNO3 per ml be diluted to yield a solution containing 16 mg AgNO3 per ml?

........oop..but i also got d same answer....1.5 ml of water per ml soln..
...but method iz different ..
as NV = constant.
N1V1 = N2V2
0.2353 V1 = 0.0941(V1+V)
=> 2.5 = 1ml + V / 1ml
=> V = 1.5ml
