In this experiment, the mass of pure copper provided is 0.437 gram, and then it was dissolved in nitric acid. An ammonia solution was added into it and transferred to a 100mL volumetric flask and dilute to 100ml with distilled water. This is the original standard solution. Then a diluted solution was prepared by adding 16 mL original standard solution to a 100ml volumetric flask and diluting to 100ml with distilled water. Please calculate the copper molarity of the diluted solution.
