Using the values you calculated for each of the trials, calculate an average value of Kf. Report your result to 3 significant figures. You will use this average value in the calculations for part III. (Just a reminder, while temperatures are expressed as oC on the Celsius scale, when a difference between two temperatures is taken, the result is expressed in Kelvins because the unit size of differences on the Celsius scale are identical to those on the Kelvin scale.)
