You want to prepare a solution of 0.500 M FeCl2 (). How many grams of FeCl2 do you need to weigh out if you are preparing your solution in a 100.0-mL volumetric flask? 

You prepared a solution by dissolving in enough water to make 500.0 mL of solution. Calculate the molarity of that solution. Enter numbers and decimal points ONLY.  Enter three significant digits past the decimal point.  Your answer should be four significant digits total. DO NOT enter M, it is known that your answer is in M.
