The volume : V₁ = 1.29 ml

<h3>Further explanation</h3>

Given

V₂=450 ml

M₂=0.02

M₁=7.0

Required

V₂

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

n₁=n₂

Dilution formula :

M₁V₁=M₂V₂

Input the value

V₁= (M₂V₂)/M₁

V₁ = (0.02 x 450)/7

V₁ = 1.29 ml
