3. What is the pressure acting on the diver by the sea water at the depth of 40m below the sea surface. The densities of sea water and pure water are 1.1 and 1.00 gem? Answer according to the following procedure. 1) Fill the parentheses latm =( ) bar = ( Spas = ( )( )( )cm H,0 2) What is the depth of pure water equivalent to the depth of 40m of sea water showing the same pressure? 3) What is the pressure in atm and pas ? 4. Calculate the pressure and composition of air cookm above the Surface of the earth assuming that the atmosphere has a temperature of oc mdependent of altitude. $. A vessel contains Hz, lz and Nz . The volume of the vessel is Il and the temperature 7829C. The partial pressures are prin 100 minity, Po, 200 mmity, and Pu2 300 mmHg, D temperature increased to 400K, Calculate the partial pressure of each component, , 2) Calculate the mole fractim of each componeut at 400k. The
