Estimate the solubility of oxygen and nitrogen in the air to water at 25oC and 1atm using Henry's law and Raoult's law. At this time, answer the following questions.

1) Determine the coefficients before the Henry constant of water for oxygen and nitrogen in the air. However, the pressure is in units of atm and the temperature is in units of K

2) Estimate the vapor pressure of water at 25oC using the following modified Antoine vapor pressure formula.

3) Apply Henry's law and Raoult's law above to estimate the solubility of oxygen and nitrogen in the air in water under conditions of 25oC and 1atm.

lnHi(atm)=C1+TC2+C3lnT+C4P lnHi(atm)=C1+TC2+C3lnT+C4TC3
