How calculate the mass of iron 2 sulfate?

To calculate the mass of iron (II) sulfate (FeSO4), you would first find the Atomic Mass of each element (iron, sulfur, and oxygen) using the Periodic Table. Then, add the atomic masses of each element (Fe + S + 4O) to find the molar mass of FeSO4, which is approximately 151.91 g/mol. Finally, you can then calculate the mass of FeSO4 by multiplying the molar mass by the number of moles.
