Question
please help. find the percent error. thank you
la. Draw a smooth best-fit curve and indicate Tr and T, on the graph. We are going to assume that the heat of solution is instantaneous with ideal mixing. The initial temperature T) is obtained from the first data point. The final temperature CTo for the exothermic solute is the highest tempersture reached. The Tr for the endothermic solute is the lowest temperature reached. Submit a graph and data table for CaCl and NH.CL Data Table-all calculations are to be done with the Measure Net data. Show sample calculations for both compounds.

Explanation / Answer
We know that the % error = mean value - observed value / mean value * 100
= [17.3 - 16.695] / 16.695 * 100 = 3.62%
