5) Determine the freezing point depression constant Kf for t-butanol. (5 pts) You must write out the following calculations by hand. Please copy and paste photos of the handwritten calculation into this Word document. a. The literature value for the freezing point depression constant Kf is 8.37 C/m. How far off is the freezing point depression constant that you determined in this experiment compared to the literature value. What it the percent error? Solve for the freezing point Troft-butanol solvent and t-butanol solution. (5 pts) You must write out the following calculations by hand. Please copy and paste photos of the handwritten calculation into this Word document. . Using the equations from the graph, determine the point as which the two line intersect. Note that you plotted time on the x-axis and temperature on the y-axis. First set each equation equal to x. Then set the two equations equal to one another and solve for y or the temperature. Copy and paste image of the handwritten calculations for at least one of the graphs into this Word document.
