1) Please could you help me answering these questions step by step
Determine the solubility (M) of oxygen in water at 25 ° C and at a partial pressure of 190 Torr. KO2 = 3.30x107 Torr. Tip: Approximate the number of total moles to the number of moles of water. Answer = 3.2 x 10-4 M 2) Calculate the ideal solubility in molar fraction of benzoic acid at 25 ° C. the melting point of benzoic acid is 122 ° C and the heat of fusion is 4139 cal / mol.
