Explain how hydrogen bonding contributes to water's high heat of vaporization

A 100.0 ml flask contains 510. g of N2 at 0 degrees c. What is the pressure in atm, torr, psi

The solubility of nitrogen gas at 25 degrees C and 1 atm is 6.8 x 10^ (-4) mol/L. If the partial pressure of nitrogen gas in air is 0.76 atm, what is the concentration (molarity) of dissolved nitrogen? 5.2 x 10^ (-4) M 1.1 x 10^ (-5) M 4.
