3.4.1 Accuracy:
Accuracy refers to how close the measured values are in agreement with that of the true values. A comparison of the actual EMO molar concentrations taken to those of predicted by equation 1 and2 (Table 1 ) shows an acceptable agreement with the standard deviation value of up to ± 6 % (equation 1 ) and ± 2 % (equation 2 ). As equation 2 showed better acceptable results, it could be employed to quantify the EMO in MO and EMO mixture.
