Question

How much cuso4 . 5 h2o is required to prepare 500



c.c if 0.5 n solution?

Answer 1

Molecular weight of CuSO4.5H2O

=> 63.5 + 32 + 4X16 + 5X18

=>249.5

To prepare 1N solution

we have to dissolve ,= 249/5/2 gm

= 124.75 gm

so to prepare 500 cc ,1N solution, 124.75/2

=>62.375 gm

So to prepare 500 cc 0.5N soluiton

= 62.375 X 0.5=31.88
