Question

An ammonia (NH3) solution composed of 28.0 g NH3 for every 72.0g water flows into a 500.0 gallon tank. The density of thissolution density= 0.8980 g/mL.

a) What is the molarity of this solution?

b) If you need to fill the 500.0 gallon tank in 150.0 s, what isthe flow rate of ammonia solution into the tank?

c)How many moles of ammonia are in the tank when it isfilled?

d) Before the ammonia solution enters the tank, it flows througha 20.0 m long pipe with a cross-sectional diameter of 10.0 cm. Atthe flow rate you calculated above, how long would it take, onaverage, for the solution to flow between the pipe inlet andoutlet?
