The number of mole of NaCl required to prepare the solution is 0.467 mole

What is molality?

The molality of a solution is simply defined as the mole of solute per kilogram of water. It is expressed mathematically as

Molality = mole / mass (Kg) of water

How to determine the mole of NaCl required

  • Molality = 0.875 M
  • Mass of water = 534 g = 534 / 1000 = 0.534 Kg
  • Mole of NaCl =?

Molality = mole / mass (Kg) of water

0.875 = mole of NaCl / 0.534

Cross multiply

Mole of NaCl = 0.875 × 0.534

Mole of NaCl = 0.467 mole
