Calculate the mass of oxygen (in mg) dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air. Assume the mole fraction of oxygen in air to be 0.21 and the Henry’s law constant for oxygen in water at this temperature to be 1.3 × 10-3 M/atm. The molar mass for oxygen is 16.00 g/mol.

At a certain temperature the equilibrium constant, Kc, equals 0.11 for the reaction:2 ICl(g) ⇌ I2(g) + Cl2(g)What is the equilibrium concentration of ICl if 0.75 mol of I2 and 0.75 mol of Cl2 are initially mixed in a 2.0-L flask?
