Step-by-step explanation:
Using the information provided, we can calculate the freezing point of the solution (FPsolution) using the formula:
FPsolution = FPwater - ATf
Where:
- FPwater = 0.00°C (freezing point of pure water)
- ATf = 5.58°C (change in freezing point due to the solute)
Substituting the values:
FPsolution = 0.00°C - 5.58°C
FPsolution = -5.58°C
Therefore, the freezing point of the solution (FPsolution) is -5.58°C. Note that the negative sign indicates that the solution has a lower freezing point than pure water due to the presence of the solute. Significant figures: The value of -5.58 has three significant figures since it includes a decimal point and the first non-zero digit is significant.
