alleryMolality m is defined as:
AMass per kg
BMoles of solute per kg of SOLVENT (temperature independent)
CMoles of solute per liter of solution
DSame as molarity
Answer & Solution
Correct answer: B. Moles of solute per kg of SOLVENT (temperature independent)
m = moles solute / kg solvent.
T-independent (mass doesn't change with T).
Preferred in colligative property calculations (involve temperature).
