Question

1. You dissolve 157.1 g of ammonium nitrate in a 250 mL volumetric flask and add water to the mark (call this solution A). You take 30 mL of solution A and place it in a 100 mL volumetric flask and add water to the mark (this is solution B). Next you take 50 mL of solution B and place it in a 500 mL volumetric flask and add water to the mark (this is solution C). Finally you take 10 mL of solution A, 10 mL of solution B and 10 mL of solution C and mix them to form solution D. What is the concentration (M) of solution D? (see problem 6 in Zumdahl test bank)
