What is the concentration of dissolved oxygen at 50°C underpressure of one atmosphere if partial pressure of oxygen at50°C is 0.14 atm.​

Answer»

Answer:

Partial pressure = Mole FRACTION × Total Pressure

Pt= 1atm

Xo2 = 0.14

Xo2 = NO2/nO2 + nH2O

nO2 + 55.5/nO2 = 1/0.14

1 + 55.5/nO2 = 7.14

55.5/nO2 = 6.14

nO2 - 9

Molarity= 9/1= 9M
