The formula to calculate the Salinity (S) is:
\[ S = \frac{MS}{MSW} \times 1000 \]
Where:
Salinity is defined as the amount of salt, in mass, in a given unit of water. The water is often referred to as saltwater or seawater. If there are 5 grams of salt in 1000 grams of seawater, the salinity in parts per 1000 would be 5 ppt.
Let's assume the following values:
Using the formula to calculate the Salinity (S):
\[ S = \frac{5}{1000} \times 1000 = 5 \, \text{ppt} \]
The Salinity (S) is 5 ppt.
