0.227L is the volume of a 3.95 M potassium chloride solution that would be needed to make 325 mL of a 2.76 M solution by dilution.
What are moles?
A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Moles of KCl in new solution
0.325dm³ x (2.76mol/dm³)
= 0.897mol.
Hence volume needed
0.897mol ÷(3.95mol/dm³)
= 0.227dm³ or 0.227L.
