Answer 1

$\huge\frak{\underline{\underline{Question:}}}$

◾️ Express concentration of solutions in different units.

$\huge\frak{\underline{\underline{Answer:}}}$

Thus, if one gram molecule of a solute is present in 1 kg of the solvent, the concentration of solutions is said to be one molal. The unit of molarity is mol kg-1. Molality is the most convenient method to express the concentration of solutions because it involves the mass of liquids rather than their volumes.
