Astudent takes a measured volume of 3.00 mhcl to prepare a 50.0 ml sample of 1.80 m hcl. what volume of 3.00 m hcl did the student use to make the sample?

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
