ANSWER:Solution: Here, we are going to calculate the volume of stock solution used to prepare 1000 mL of 0.250 M ammonia. Also, we are going to find the concentration of the final solution if 10 mL of the stock solution is diluted to 0.500 L. Step1: In order to dilute a stock solution, we have to use the following dilution equation, M 1 1M V 2 2 -----------(1) Here, M an1V are t1 molarity and volume of the concentrated stock solution whereas M and 2 V are the molarity and volume of the diluted solution. 2 S
