A sample contains an unknown amount of the mineral siderite, FeCO3. If 0.6050 g of the sample requires 40.08 mL of 0.1000 M HCl to neutralize the FeCO3 completely, what is the percentage of FeCO3 in the sample? The molar mass of FeCO3 is 115.86 g/mol. The balanced equation for the reaction is: FeCO3 + 2 HCl → H2O + CO2 + FeCl2
