724 mmHg 8℃ CO 1.20 g volume (L)

724 mmHg 8℃ CO 1.20 g volume (L)

 

 

What is the volume, in liters, of 1.20 g of carbon monoxide

at 8℃ if it has a pressure of 724 mmHg?

 

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

 

CO의 몰질량 = 12 + 16 = 28 g/mol 이므로,

1.20 g / (28 g/mol) = 0.042857 mol CO

( 참고 https://ywpop.tistory.com/7738 )

 

 

 

PV = nRT 로부터,

( 참고 https://ywpop.tistory.com/3097 )

 

V = nRT / P

= [(0.042857) (0.08206) (273.15+8)] / (724/760)

= 1.0379 L

 

 

 

답: 1.04 L
