An aqueous solution of sodium hydroxide contains 20% naoh by mass. it is desired to produce an 8% naoh solution by diluting a stream of the 20% solution with a stream of pure water.(a) calculate the ratios (g h2o/g feed solution) and (g product solution/g feed ) determine the feed rates of 20% solution and diluting water needed to produce 2310 lb/min of the 8% solution.
