Calculate the number of moles in an ideal gas

trapped in a cylinder of diameter .7 cm and a height of 10 cm,

when pressure is at 1555 N/m2 at 6600 K.

원기둥의 부피(V)

V = πr^2h

= (3.14159) (.7/2 cm)^2 (10 cm)

= 3.84845 cm^3

= 3.84845 mL

= (3.84845/1000) L

 

 

 

1555 N/m2 = 1555 Pa

 

1555 Pa × (1 atm / 101325 Pa)

= 0.015347 atm

 

 

 

PV = nRT 로부터,

( 참고 https://ywpop.tistory.com/3097 )

 

n = PV / RT

= [(0.015347) (3.84845/1000)] / [(0.08206) (6600)]

= 1.09×10^(-7) mol

 

 

 

답: 1.09×10^(-7) mol
