Empirical relation between mean median and mode. The mode is the number that is repeated more often than any other so 13 is the mode. Via this equation if the values of two measures are known we can find the third measure.
In chemistry the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound.
Mode 3 median - 2 mean. In such situations mode is calculated by the following formula. The two compounds should form a definite whole number ratio by mass. Hence the median is 14.
