Question: A 20 wt% H2S04 solution (density = 1.139 g/cm3) is mixed with a 60 wt% H2S04 solution (density = 1.498 g/cm3), in order to obtain

A 20 wt% H2S04 solution (density = 1.139 g/cm3) is mixed with a 60 wt% H2S04 solution (density = 1.498 g/cm3), in order to obtain a H2S04 solution with the concentration of 4.0 mol/L. Determine

(a)the ratio between the 20 wt% H2S04 solution and 60 wt% H2S04 solution, in order to get the acid solution with the desired concentration

(b)the amount of the 60 wt% H2S04 solution needed if 1,250 kg of 4.0 mol/L H2S04 solution is required. (MW of H2S04 and of water are 98.08 and 18.02, respectively)
