Stoichiometric equations are used to represent growth of microorganisms provided a ' molecular formula' for the cells is available. The molecular formula for biomass is obtained by measuring the amounts of C, N, H, O and other elements in cells. For a particular bacterial strain, the molecular formula was determined to be C_4.4H_7.30 _1.2N_0.86 . These bacteria are grown under aerobic conditions with hexadecane (C₁₆H₃₄) as substrate. The reaction equation describing growth is:

  Assuming 100% conversion, what is the yield of cells from hexadecane in g g^-l?
