Calculate the weight of methane in a `9 L` cylinder at `16 atm` and `27^(@)C` temperature. (`R=0.08 L atm K^(-1)mol^(-1)`)

Options

A. 96 gm
B. 86 gm
C. 80 gm
D. 90 gm

Answer

A

Explanation

Given P =16 atm, V = 9 litre
T =300 K,`m_(CH_(4)) = 17, R =0.08` litre atm `//`k.
`PV =w//m xx R xx T `
`16 xx 9 = ( w)/( 16) xx 0.08 xx 300`
`w =96 ` gm
