Question

DEFINE THE FOLLOWING TERMS.....
# molarity
#molality
#mole fraction..


NO spams..... Plz give qualitied answer.... ​

Answer 1

here is your ans......

molarity: molarity is the no of moles of solute dissolved per litre of solution.

molality: molality is the number of moles of solute per kilogram of the solvent (not solution)

mole fraction:mole fraction is defined to be equal to the no of moles of a component divided by the total number of moles of a solution . it is a unitless expression.

hope this will help you

Answer 2

Answer:

✔Molarity:

➡Molarity is defined as number of moles of solute dissolved in 1 litre of the solution.

➡It is denoted by M.

➡Unit of molarity is mol/litre

➡Molarity of a solution depends uoon temperature.

⭐Molarity (M) =

• No.of moles of solute/volume of solution in litres.

✔Molality:

➡Molality is defined as number of moles of solute present in 1 kg of the solvent.

➡It is denoted by m.

➡Unit is mol/kg

➡Molality of a solution does not depend on temperature.

⭐Molality=No.of moles of solute/mass of sopvent in kg

✔Mole fraction:

➡It is the ratio of number of moles of a particular compound to the total number of moles in the solution.
