Benzene is stored in an open rectangular tank with the dimensions of 5 m length, 7 m width and 10 m height. A 15 mm stagnant air film is covering the benzene surface beyond which benzene is absent. At the atmospheric temperature of 25 C, its corresponding vapour pressure is 150 mm Hg, calculate the rate loss of the benzene in kmol/s. Given the diffusivity of benzene is 0.02 m2 /h and total pressure is 1.0 atm.

An aqueous solution of potassium hydroxide is standardized by titration with a 0.194 m solution of hydrobromic acid. if 25.2 ml of base are required to neutralize 24.2 ml of the acid, what is the molarity of the potassium hydroxide solution? m potassium hydroxide
