Question

in which of the following does not depend upon the temperature a,molarity b,normality c,formality d,molality

Answer 1

ans is d hope its helpful

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

Molarity is defined as the number of moles of solute present in one liter of solution. When we increase the temperature then there will be decrease in volume. Hence, change in temperature will affect the molarity.

Normality is the number of gram equivalent per liter of the solution. As it also depends on volume hence, with change in temperature there will be change in normality of the solution.

The number of gram formula masses of the ionic solute dissolved in per liter of solution is known as formality. Since, volume is involved here. Therefore, temperature also affects formality.

Molality is defined as the numbe rof moles of solute per kg of solvent. Since, mass is involved here and it remains the same whether there will occur any change in temperature or not.

Thus, we can conclude that out of the given options, molality does not depend upon the temperature.
