A 10 wt% aqueous sulfuric acid solution, = 1.03 g/ml, flows through a 45 m long pipe with a 6 cm inside diameter at a rate of 100 L/min. Determine the

a) molarity of the sulfuric acid in this solution (i don't need it).

b) time (s) it would take to fill a 55 gallon drum (i don't need it).

c) mass of water in the pipe (kg). should be 117.9

d) mass flow rate of water out of the pipe (kg/min). should be 92.7

e) component molar flow rate of HSO out of the pipe (mols/min). should be 105

I need help with c, d, and e.
