Question

Some water is added to a mixture of 250 ml of 0.6 M HCl and 750 ml of 0.2 M HCl to obtain 0.25 M solution of HCl as a resulting solution. Then

Options

A.The volume of water added is 200 ml
B.The volume of water added is 100 ml
C.Total mass of HCl in the solution is 10.95 g
D.Total mass of HCl in the solution is 18.25 g.

Solution

Let V ml water is added
⇒   0.25 =
⇒  V = 200 ml
also mass of HCl = × 36.5 = 10.95 g
