How do you calculate the osmolarity of seawater?
You add up the molarities of the constituent ions.
The composition of seawater varies around the world, but the concentrations of the six most abundant ions in a "typical" sample are:
If you include the magnesium, calcium, potassium, and sulfate ions, the osmolarity is closer to 1200 mOsmol/L.

The osmolarity of seawater can be calculated by summing the concentrations of all solutes dissolved in the seawater, including salts, gases, and other dissolved substances. This is typically measured in moles of solute per liter of seawater (mol/L). The primary components contributing to seawater osmolarity are sodium chloride (NaCl), magnesium sulfate (MgSO4), calcium chloride (CaCl2), and potassium chloride (KCl). By quantifying the concentrations of these solutes and accounting for their respective contributions to total osmolarity, the osmolarity of seawater can be accurately calculated.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
