For this question, assume that you added exactly the volumes of all reagents as listed in the table. (Remember that the stock solution concentration is 50.00 ppm.) Show all your work carefully using good form and significant figures. Note that you will find the information on p. 16 to be useful here. [SF = 2, FORM = 3, ANS = 1]
