To calculate the empirical formula enter the composition eg. However in statistics we often need to find area under the bell curve for standard deviations that are not whole for example from 235 standard deviations below the mean to 14 standard deviations above the mean. For example if you want to calculate 25 of 50 multiply 25 by 50.

From the empirical formula you can work out the molecular formula if you know the relative formula mass M r of the compound.

If youre given the Percent Composition of a compound you can find the Empirical Formula for it. You can find the empirical formula of a compound using percent composition data. For example if a compound is 4092 percent carbon multiply 4092 by 12 its atomic mass to get 34. Because the Empirical rule gives percentages for 1 2 and 3 standard deviations the Empirical Rule Calculator is useful for finding percentages for whole standard deviations.
