Question

How Will prepare 0.25m cacl2 solution

Answer 1

We know that molarity is the no of moles per unit volume. From following relation we can calculate amount of cacl2 required (X)to prepare 0.25 M cacl2 250 ml solution. Hence by dissolving 6.9375 g of cacl2 in 250 ml volumetric flask with distilled water then you will get 0.25 M cacl2 solution
