An ammonia (nha) solution composed of 20.0 g nha for every 80.0 g water flows into a 480.0 gallon tank mapdb the density of this solution is p 0.9229 g/ml. what is the molarity of this solution? number mol nh, l if you need to fill the 480.0 gallon tank in 160.0 s, what is the flow rate of amimonia solution into the tank? number m'/s how many moles of ammonia are in the tank when it is filled? number mol nh, before the ammonia solution enters the tank, it flows through a 31.0 m long pipe with a cross-sectional diameter of 10.0 cm. at the flow rate you calculated above, how long would it take, on average, for the solution to flow between the pipe inlet and outlet?
