Answer:
-4.1°C
Explanation:
The freezing-point depression (ΔTf) is a colligative property that can be calculated using the following expression:
ΔTf = i × Kf × m
where,
i: van't Hoff factor
Kf: freezing-point depression constant
m: molality
ΔTf = 1.9 × 1.86°C/m × 1.15 m = 4.1 °C
The freezing-point of pure water is 0°C. The freezing-point of this solution is:
0°C - 4.1°C = -4.1°C

Dark structures do not show the distribution of electrons in orbitals and take up a lot of space.
When they become a solid, as in a solid the particles are packed tightly together and have little space between them, thus at solid state , particles are more ordered.
