A chemistry student needs to determine the percent by mass of magnesium (Mg) in a sample of limestone. The student has access to 5 grams of the sample and is provided with the following information: the sample is comprised of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3); the atomic masses of the elements are: Ca = 40.08 g/mol, C = 12.01 g/mol, O = 16.00 g/mol, and Mg = 24.31 g/mol; and the sample contains a total of 3.06 grams of carbon (C). Calculate the percentage by mass of magnesium in the limestone sample using mass balance calculations.
