What is the temp. in K, of

1.13 g of O2(g) (MW = 32.00) in a 44.8 mL

rigid, sealed flask at 7.59 atm?

 

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

 

PV = nRT

( 참고 https://ywpop.tistory.com/3097 )

 

T = PV / nR

= [(7.59) (44.8/1000)] / [(1.13/32.00) (0.08206)]

= 117 K

 

 

 

[참고]

n = W / M

( 참고 https://ywpop.tistory.com/7738 )

= 1.13 g / (32.00 g/mol)

= 1.13/32.00 mol

 

 

 

[참고]

117 273 = -156
