An anaerobic digestion system is operated for methane gas generation from organic fraction of municipal solid waste $\text{(OFMSW)}$. The moisture content and volatile solids $\text{(VS)}$ content of $\text{OFMSW}$ are $20 \%$ and $90 \%$, respectively. The biodegradable volatile solids $\text{(BVS)}$ in the $\text{VS}$ is $70 \%$, and the $\text{BVS}$ conversion efficiency to methane gas is $85\%$.
If the methane gas generation in the system is $12 \mathrm{~m}^{3}$ per kg of $\text{BVS}$ converted, the total volume of gas produced from one kilogram of $\text{OFMSW}$ is $\_\_\_\_\_\_$ $\mathrm{m}^{3}$ (rounded off to two decimal places).
