<span>FeCl3 ---> Fe3+ + 3Cl-
AS
1mol FeCl3 produces 3mol Cl-
so
0.250LCl- * 0.300molCl-/1LCl- * 1molFeCl3/3molCl- * 1LFeCl3/0.175molFeCl3
= 0.1428LFeCl3 =
142.8mlFeCl3
hope it helps</span>

The volume of FeCl₃ needed to make 250 mL of 0.3 M in Cl⁻ ions was 142,857 ml

<h3><em>Further explanation</em></h3>

Dilution is the process of adding solvents (generally water) which aims to obtain a solution with a concentration that is smaller than the initial concentration of a more concentrated substance.

So the principle of dilution is to get a lower / dilute concentration.

At dilution the number of dissolved moles before and after dilution is the same

The dilution formula is as follows:

$\large {\boxed {\bold{M_1 \: \times \: V_1 ~ = ~ M_2 \: \times \: V_2}}$
