a student is asked to determine the concentration of a solution of NaOH. the student performs 4 analyses of the solution and obtains concentrations of 0.1106M, 0.1058M, 0.1122M and 0.1022M. determine the average deviation and the relative average deviation for this student's data. if the actual concentration of the solution is 0.1025M, calculate the absolute error and the relative error in this student's result.
