Question

calculate volume of water that must be added to 250cc of 1.25 N solution to make it 0.5N.​

Answer 1

Not that difficult as it looks..

1 cc = 1 mL

250 cc = 250mL

We have this formula of titration u know..

N1 x V1 = N2 x V2

1.25N x 250mL = 0.5N x V2

So calculate this u would get

V2 = 625 mL

I hope it helps..
