Question

Which is not affected by temperature normality for formality molarity molality?

Answer 1

Answer:Molality.

Explanation:

Molality is considered better for expressing the concentration because molality does not change with temperature because the mass of the solvent does not change with change in temperature.

Hope it helps.

Answer 2

hi mate ur answer...

MOLALITY does not depend on temperature, (Neither number of moles of solute nor mass of solvent will be affected by changes of temperature.) while MOLARITY changes as temperature changes. (Volume of solution in the formula changes as temperature changes, and that is why.) Thus, when we increase the temperature there will be change in the volume of solution or solvent. Thus, this change will affect the value of molarity and normality because both of them are dependent on volume. Whereas molality will not be affected by temperature.
