Arsenic (As) is element 33 on the periodic table. A sample contains 3.37x1026 atoms of As. Calculate the amount of As. mol As How many milliliters of an aqueous solution of 0.181 M aluminum iodide is needed to obtain 17.0 grams of the salt? mL In the laboratory you dissolve 22.6 g of sodium sulfate in a volumetric flask and add water to a total volume of 500 mL. What is the molarity of the solution? M You need to make an aqueous solution of 0.146 M sodium acetate for an experiment in lab, using a 125 mL volumetric flask. How much solid sodium acetate should you add? grams
