Answer:
E) molality
Explanation:
Molality -
Molarity of a substance , is the number of moles present in a Kg of solvent .
Hence , the formula for molality is given as follow -
m = n / s
m = molality
s = mass of solvent in Kg ,
n = moles of solute ,
Hence , from the given information of the question,
The concentration unit which have Kg of solvent , is molality.
