c. The relative deviation (d,) of a measurement or experimental data is the deviation divided by the mean. The relative deviation may be expressed in percent. d, d, x100 : -x100 The relative deviation may also be expressed in parts per thousand or ppt (by changing the factor 100 to 1000) or in terms of parts per million or ppm (by changing the factor 100 to 1,000,000). The choice of factor to use depends on the magnitude of the ratio. The relative deviation (ppt) of 17.29%Cu is SOLUTION: ED

The results of the analysis of a metal alloy were reported in terms of percent Cu (%Cu). The values obtained are 17.34%, 17.33%, 17.28%, 17.29%, 17.36%. The expression of the central value significant to chemists is the arithmetic mean (or average) is the sum of the measured values, x;, divided by the n, number of replicate measurements. x, +x, + x, +...+: Ex n a. The mean or the average %Cu is SOLUTION:
