In 1.00 atm of pure oxygen, the solubility of O2(g) in water is 1.26 x 10^-3 M at 25.0 degree C. The mole fraction of oxygen in air is 0.210. If the atmospheric pressure is 0.979 atm, what is the solubility of oxygen in air at 25.0 degree C?
An unknown solid compound containing Pb2+ ion was mixed with 15 mL of 2.0 M HNO3. The mixture bubbled profusely. After complete reaction, it was found that 0.020 moles of CO2 were produced and the original solid was completely consumed.
