A process stream has 100 g/L NaCl in H2O. Prior to adding this to a batch bioreactor, the concentration must be reduced to 154 mM. The specific gravity of the solution is 1.075 at 20°C.
a) What is the weight percent of NaCl?
b) What is the molarity of the process stream?
c) If the reactor holds 10,000 L of saltwater, how much pure water must be added to the process stream to obtain the required 154 mM final concentration?
d) How many pounds per cubic foot is the solution in the process stream?
