THE MOMENTS OF A RANDOM VARIABLE Definition: Let X be a rv with the range space Rx and let c be any known constant. Then the kth moment of X about the constant c is defined as Mk (X) = E[ (X c)k ]. (12) In the field of statistics only 2 values of c are of interest: c = 0 and c = . Moments about c = 0 are called origin moments and are denoted by k‚ i.e.‚ k = E(Xk )‚ where c = 0 has been inserted into equation (12). Moments about the

Experiment 3: Solution Calorimetry: Thermodynamics of Potassium Nitrate II. Abstract A determination of thermodynamic variables of KNO3 is presented. KNO3 was heated and dissolved in varying volumes of distilled water. Upon dissolution‚ the KNO3 solution was removed from heat and the temperature was recorded once crystals formed. For each solution‚ ∆G the Ksp were found with the temperature and molarity values. ∆H and ∆S were found through the linearization of the data with
