plz mark it branliest

Explanation:

Let the weight of methane (CH4) be Wgm.

Molecular mass of methane (CH4)=16

Volume, (V)=9L

Temperature, (T)=27℃=(273+27)K=300K

Pressure, (P)=16 atm

No. of moles, (n)=Mol. wt.wt.=16W

R=0.082Latmmol−1K−1

Aplying ideal gas equation, we have

PV=nRT

⇒16×9=16W×0.082×300

⇒16W=24.6144

⇒W=16×5.85

⇒W=93.6g

Hence, the weight of methne is 93.6 g.
