Answer : The maximum mass of aspartame is, 5142.3 grams
Explanation : Given,
Molal-freezing-point-depression constant 
for water = 
Mass of water (solvent) = 2.50 kg
Molar mass of aspartame = 294.3 g/mole
Formula used :
where,
= change in freezing point
= freezing point of solution = 
= freezing point of water = 
i = Van't Hoff factor = 1 (for non-electrolyte)
= freezing point constant for water =
m = molality
Now put all the given values in this formula, we get
Therefore, the maximum mass of aspartame is, 5142.3 grams
I think the correct answer from the choices listed above is the second option. If a copper atom loses two electrons, the name of the copper ion is copper (II) ion . Also it is called cupric acid. However, the latter <span>is an old term and is not recommended. Hope this answers the question.</span>
The electron is the part of an atom that is either gained, lost, or shared during a chemical reaction.
