For a biodegradable waste with a chemical formula $\mathrm{C}_{50} \mathrm{H}_{100} \mathrm{O}_{40} \mathrm{~N}$, the maximum theoretical methane production per ton of waste is __________ $\mathrm{kg}$ $\text{(rounded off to $2$ decimal places)}$.
Assume $100 \%$ anaerobic conversion. Atomic weights of $\text{C-12; H-1; O-16; N-14}$
