Anhydrous Magnesium Sulfate Molecular Weight

The molecular formula for anhydrous magnesium sulfate is MgSO4. Anhydrous means it does not contain any water molecules. To calculate the anhydrous magnesium sulfate molecular weight, you need to add up the atomic weights of all the atoms in the formula.

The atomic weights of the elements are as follows:

Magnesium (Mg): 24.305 atomic mass units (amu)
Sulfur (S): 32.06 amu
Oxygen (O): 16.00 amu

The molecular weight of anhydrous magnesium sulfate can be calculated as:
(1 × Mg) + (1 × S) + (4 × O)

Substituting the atomic weights:
(1 × 24.305 amu) + (1 × 32.06 amu) + (4 × 16.00 amu)

Calculating the values:
24.305 amu + 32.06 amu + 64.00 amu

Anhydrous magnesium sulfate molecular weight is approximately 120.365 amu (or g/mol). Keep in mind that this value is an approximation since atomic weights can have slight variations depending on the source.
