How is density affected when the salinity increases?

When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases.

Salinity describes how much salt is dissolved in a sample of water. The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.
