**Freezing Point Depression versus Molality****Graph and Equation Analysis**The above image depicts a graph titled "Freezing point depression versus molality." The graph is a linear plot that shows the relationship between the freezing point depression (ΔTf) of a solution and its molality (m). - **X-axis (horizontal):** It represents the molality (m) of the solution, ranging from 0 to 5.- **Y-axis (vertical):** It indicates the freezing point depression (in Kelvin, K), ranging from 0 to 30.The data points on the graph form a linear pattern, indicating a direct proportionality between the freezing point depression and the molality. The equation of the line, given as y = 6x, represents this relationship where:- **y:** Freezing point depression (ΔTf)- **x:** Molality (m)- **Slope:** 6, meaning for each unit increase in molality, the freezing point depression increases by 6 K.**Lab Exercise**In this scenario, a student is required to determine the van't Hoff factor (i) for a deicer dissolved in water. To achieve this, the student prepares six solutions with different molalities.- **Freezing point depression constant for water (Kf):** 1.86 K·m^-1**Task:**Calculate the van’t Hoff factor (i) using the provided data and the freezing point depression equation.\[ \Delta T_f = i \cdot K_f \cdot m \]Given that the slope of the line (represented by 6 in the equation y = 6x) is equal to the product \( i \cdot K_f \), solve for \( i \):\[ 6 = i \cdot 1.86 \]\[ i = \frac{6}{1.86} \]**Determine the van't Hoff factor (i):**\[ i = \boxed{\_\_\_\_} \]

In the given graph x axis represent molality and y axis represent freezing point depression.…
