Elemental formula and molar mass

Atomic coefficient of element k in biomass formula (x ) is calculated as follows  

Calculation of the degree of reduction and generalized degree of reduction was presented in equations (22) and (25), respectively. The low value of the atomic coefficient of sulfur in biomass has a low influence on the degree of reduction. 

The mass of 1 C-mol of biomass is calculated from the carbon content as,
