Question

What volume of a 0.125M NiCl2 solution contains 3.25g NiCl2?

Answer 1

Answer:201L

Explanation:

Answer 2

Answer:

• The volume of NiCl2 can be calculated using the formula of molarity.
• Moles of solute per unit volution of the solution is defined as molarity.

        Molarity (M) = n/V, where

       n= no. of moles of the solute.

       V= volume of the solution in liters.

• In the question, we know

        Molar mass of NiCl2= 129

        Molarity of NiCl2= 0.125M

        n = 3.25/129 = 0.02519

        M = n/V

        0.125 = (0.02519/V)×1000

        V = 201 L

Hence, the volume of NiCl2 is 201 L.
