Step-by-step explanation:
To find the freezing point of the solution using the freezing point depression (ATf) and the freezing point of water, we can use the equation:
FPsolution = FPwater - ATf
where FPwater is the freezing point of pure water (0.00 °C). We know that ATf for this solution is 5.58 °C, as found in the previous step. Therefore:
FPsolution = 0.00 °C - 5.58 °C
FPsolution = -5.58 °C
However, a freezing point below zero degrees Celsius is not physically possible, since water freezes at 0.00 °C. Therefore, the solution would not actually freeze at this temperature, and we need to round the answer to zero °C:
FPsolution ≈ 0.00 °C
Therefore, the freezing point of the solution is around 0.00 °C, or the solution will not freeze at this temperature.
