Raw municipal solid waste (MSW) collected from a city contains $70 \%$ decomposable material that can be converted to methane. The water content of the decomposable material is $35\%$. An elemental analysis of the decomposable material yields the following mass percent.

$$ \text{C : H : O : N: other} = 44: 6:43:0.8:6.2$$

The methane production of the decomposable material is governed by the following stoichiometric relation

$$C_aH_bO_cN_d + _nH_2O \to _mCH_4 + _sCO_2+dNH_3$$

Given atomic weights: $C=12, \: H=1, \: O=16, \: N=14$. The mass of methane produced (in grams, round off to $1$ decimal place) per kg of raw MSW will be _________
