How to Calculate Mole Fraction
We calculate the mean and standard deviation for each years annual increase from the ensemble members and one standard deviation from the two terms network and analytical is taken in quadrature to give the reported uncertainty at each time step. Because the individual masses of the ingredients of a mixture sum to their mass fractions sum to unity.
