At 298 K, what is the solubility of oxygen in water exposed to air at 1.00 atm? Number At 298 K, what is the solubility of oxygen in water exposed to air at 0.893 atm? Number If atmospheric pressure suddenly changes from 1.00 atm to O.893 atm at 298 K, how much oxygen will be released from 5.30 L of water in an unsealed container? Number mol O Previous ® Give, Up & View Solution 9 Check Answer 0 Next I ExitExplanation / Answer
C = KH * P
KH = 0.0013M/atm
P = 1*21/100 = 1*0.21 = 0.21atm
C = 0.0013M/atm*0.21atm = 0.000273M
2.
C = KH * P
KH = 0.0013M/atm
P = 0.893atm*21/100 = 0.893*0.21 atm = 0.18753atm
C = KH * P
= 0.0013M/atm*0.18753atm
= 0.000243789M
3.
no of moles = molarity * volume in L
= 0.000273*5.3 = 0.0014469 moles
no of moles = molarity * volume in L
= 0.000243789 *5.3 = 0.001292moles
no of moles change = 0.0014469 - 0.001292 = 0.0001549 moles >>>>answer
