Answer» QUESTION : 2 molal NaOH solution has TEMPERATURE 298 K. if temperature of the solution is 323 K. concentration GIVEN : Molality (m 1 ) = 2 m Temperature (T 1 ) = 298 K Temperature ( T 2 ) = 323 K SOLUTION : As PER the FORMULA , molality = moles of solute / mass of the solvent mass doesn't DEPEND upon temperature hence ,molality also doesn't depend upon temperature hence , at 323 K the molality remains the same molality ( m 2 ) = 2 m ANSWER : molality = 2 m

QUESTION :

2 molal NaOH solution has TEMPERATURE 298 K. if temperature of the solution is 323 K. concentration

GIVEN :

SOLUTION :

molality = moles of solute / mass of the solvent

mass doesn't DEPEND upon temperature

hence ,molality also doesn't depend upon temperature

hence , at 323 K the molality remains the same

molality ( m 2 ) = 2 m
