A 7,030 kg-mole ethyl acetate aqueous solution containing 85-mole % (mol %) water is added to a 69-w % ethyl acetate aqueous solution to obtain 52-w % ethyl acetate aqueous solution. Find the mean molecular weight of the 7,030 kg-mole ethyl acetate aqueous solution. Calculate the amounts (kg) of the 69-w % ethyl acetate aqueous solution and the 52-w % ethyl acetate aqueous solution using the Chemical Engineering Handbook

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
