Calculate the number of moles of gaseous nitrogen contained in a sample of 227 mL of gas saturated with water vapour at 20 °C and 90.0 kPa.
Hint: Find the volume of pure hydrogen then convert this volume to NTP conditions and find the number of moles. (The change in pressure applies to the pressure exerted on the gas; it'll vary between 90 kPa and 101.3 kPa even if the partial pressure of the nitrogen is less than 90 kPa.)
Determine the solubility of N2 in water exposed to air at 25 C if the atmospheric pressure is 1.2 atm. Assume that the mole fraction of nitrogen is 0.78 in air and the Henry's law constant for nitrogen in water at this temperature is 6.1 10-4 M/at..
