Water begins flowing from the roof after 35.0 minutes of rainfall. What will the rate of draining (L/s) be if rain continues to fall at the same rate?

a) Calculate the mass fraction of sulfuric acid in the product solution.

b) Calculate the feed ratio (liters 20.0 % solution/liter 80.0 % solution).

c) What feed rate of the 80.0 % solution (L/h) would be required to produce 1450 kg/h of the product? in L/h
