Oxygen gas makes up 21 % of the atmosphere by volume. What is the solubility of O2(g) in water at 25°C if the atmospheric pressure is 741 mmHg? The Henry's law constant for oxygen gas at 25°C is 1.3 x  10–3 mol/L·atm.

The solubility of oxygen in lakes high in the Rocky Mountains is affected by the altitude. If the solubility of O2 from the air is 2.67 x 10–4 M at sea level and 25°C, what is the solubility of O2 at an elevation of 12,000 ft where the atmospheric pressure is 0.657 atm?  Assume the temperature is 25°C, and that the mole fraction of O2 in air is 0.209 at both 12,000 ft and at sea level.Group of answer choices4.06 x 10–4 MNone of the above.1.75 x 10–4 M 3.66 x 10–5 M2.67 x 10–4 M

If O2 gas is bubbled through water at 303 K, the number of millimoles of O2 gas that dissolve in 1 litre of water is ________________. (Nearest integer)(Given: Henry’s Law constant for O2 at 303 K is 46.82 k bar and partial pressure of O2 = 0.920 bar)(Assume solubility of O2 in water is too small, nearly negligible)

H 2 C8H18(l) + 25 O2(g) ----> 16 CO2(g) + 18 H2O(g)How many grams of water would be produced if 3.43 liters of oxygen were burned at a temperature of 55.791°C and a pressure of 1.15 atm?

Water can be decomposed by electrolysis to hydrogen gas and oxygen gas. If 2.33 g of water is decomposed to H2(g) and O2(g) and the gases are collected in a 1.00 L flask over water at 25°C (vapor pressure H2O(l) = 23.8 mm Hg), what is the pressure in the flask?

2 H2O2(l) 2 H2O(g) + O2(g) Decompose 0.11 g of H2O2 in a flask with a volume of 2500.0 mL. What is the pressure of O2 at 25 oC? Of H2O?
