Question

a solution is prepared at 20 degrees celsius and its concentration is expressed into different units molarity and molality the solution is then heated to 88 degree celsius which of the concentration units will change​

Answer 1

Answer:

molarity

Explanation:

Molarity is defined as the number of moles of solute in 1 liter of a solution while molality is defined as the mole of solute in 1 kg of solvent.

If a solution prepared at 20 degrees celsius is heated to 88 degrees celsius, the molarity would change because the volume of a solution is temperature-dependent due to expansion or contraction. The molality, however, will not change for as long as the amount of the solvent remains unchanged due to the heating.
