Understanding Molecular Mass

Molecular mass, also known as molecular weight, is the sum of the atomic masses of all the atoms in a molecule. It is a fundamental concept in chemistry that helps in understanding the behavior of substances in chemical reactions. The molecular mass of a compound is essential for determining the amount of substance in moles, which is a key unit in stoichiometry.

Calculating the Molecular Mass of MgSO₄

To calculate the molecular mass of MgSO₄, we need to know the atomic masses of magnesium (Mg), sulfur (S), and oxygen (O). The atomic masses for these elements are approximately:

Magnesium (Mg): 24.305 g/mol
Sulfur (S): 32.065 g/mol
Oxygen (O): 15.999 g/mol

The molecular formula MgSO₄ indicates that there is one atom of magnesium, one atom of sulfur, and four atoms of oxygen. Using these values, we can calculate the molecular mass as follows:

Molecular mass of MgSO₄ = (1 × 24.305) + (1 × 32.065) + (4 × 15.999)

Molecular mass of MgSO₄ = 24.305 + 32.065 + 63.996

Molecular mass of MgSO₄ = 120.366 g/mol

Therefore, the molecular mass of MgSO₄ is approximately 120.366 grams per mole.
