A student performs the following gravimetric analysis of iron ions in a water system:Fe2+ (aq) + 2CO32- (aq) = FeCO3 (s)If this student used excess carbonate and obtained the following data, what was the original concentration in moles/L) of Fe2+ in the water sample? Total Volume of Solution: 100.00 mLMass of FeCO3 collected: 23.758 grams.Is this how you would solve it change 100 ml to .1 liters. 115.853x = 23.758 x .1 = .02 liters.
