The volume required : 0.2 L

<h3>Further explanation</h3>

Given

500ml of 0.1M potassium dichromate (vii)

0.25 solution

Required

The volume

Solution

We can use dilution formula :

M₁V₁=M₂V₂

M₁ = 0.25

M₂ = 0.1

V₂ = 500 ml = 0.5 L

The initial volume taken :

V₁=(M₂V₂)/M₁

V₁=(0.1 x 0.5)/0.25

V₁=0.2 L
