Question:

An insulated tank, open to the atmosphere, contains l,500(lbm) of 40-wt-% sulfuric acid at 60(°F). It is heated to 180(°F) by injection of live saturated steam at 1 (atm), which fully condenses in the process. How much steam is required, and what is the final concentration of H2SO4 in the tank?
