Look on the periodic table and add them up.
Take the mass of Iron and multiply it by 2, then get the mass of Sulfur and multiply it by 3, then get the mass of Oxygen and multiply it by 12 and then add them up. Once you have that mass, then you have its "molar mass" so just multiply the molar mass by the amount of mols!
