Answer 1

Mole fraction

pls mark me as brainliest and follow me ✌️

Answer 2

Answer:

Two solutions having the same molalities will also have the same mole fraction.

Explanation:

• The mole fraction of a single component is the ratio of that component's moles to the total moles of all components present in the solution.

       When n₁ moles of component 1 and n₂ moles of component 2 are       mixed to produce a solution, the mole fractions of components 1 and 2 are:

       χ₁ = n₁/(n₁+n₂) and χ₂ = n₂/(n₁+n₂).

• A solution's molality is defined as the number of moles of solute dissolved per 1000 g of solvent.

The mole fraction of two solutions with the same molalities will be the same.

Because of changes in densities, molarity and normality may differ.
