Respuesta :

I would say that this is a hydrate, so the "n" stands for how many H2O's are bonded to the magnesium sulfate resulting in the name of Magnesium Sulfate  N-Hydrate (N being the appropriate prefix pertaining to the number n).

Answer:

In the formula MgSO4·nH2O, the 'n' represents the number of water molecules (H2O) that are associated with each formula unit of magnesium sulfate (MgSO4). It indicates that the compound has a variable amount of water molecules bound to it, depending on the specific conditions such as temperature and humidity.
