In dilution we add distilled water to decrease the concentration of required sample from high concentration to lower concentration

The law used for dilution:

M₁V₁]Before dilution = M₂V₂] After dilution

M₁ = 1.5 M

V₁ = ?

M₂ = 0.3 M

V₂ = 500 ml

1.5 * V₁ = 0.3 * 500 ml

so V₁ = 100 ml and it completed to 500 ml using 400 ml deionized water
