Thus, your answer.
Answer:
Molality for this solution is 0.98 mol/kg
Explanation:
ΔT = Kf . m . i
Freezing point depression, here
ΔT = Freezing point of pure solvent - Freezing point of solution
i = Van't Hoff factor.
This solute, the amino acid glycine does not ionize, so the i in this case is 1
Let's replace the data given
0° - (-1.83°C) = 1.86 °C/m . m . 1
1.83°C = 1.86 °C/m . m . 1
1.83°C / 1.86 m/°C = 0.98 m
Exothermic is when heat escapes an object. So the answer should be the last one.
