42 L methane 35℃ 360 psig methane kg ideal gas

 

---------------------------------------------------

 

psia = psig + 14.696 psia

( 참고 https://ywpop.tistory.com/8669 )

 

= 360 + 14.696

= 374.696 psia

 

 

 

374.696 psia × (1 atm / 14.696 psia)

= 25.496 atm

 

 

 

PV = nRT

( 참고 https://ywpop.tistory.com/3097 )

 

n = PV / RT

= [(25.496) (42)] / [(0.08206) (273.15+35)]

= 42.347 mol

 

 

 

42.347 mol × (16 g/mol) = 678 g

= 0.678 kg
