In the deep ocean, huge masses of water circulate around the globe, driven by differences in temperature and salinity. This is called the thermohaline circulation, sometimes also known as the global conveyor belt. Differences in temperature and salinity cause differences in ocean water density. As water warms, it expands, decreasing density.

(Hint: Use the density and molar mass of water.) What happens to the concentration of water when a solute is dissolved in it? (1000 g/L) / 18.0 g/mol = 55.6 mol/L. The concentration of water decreases as a the concentration of a solute increases because the solute occupies some of the volume and the water molecules are pushed apart. 4

A solution was made by dissolving 800.0 g of NaOH in 2.00 L of water. Calculate the molality, mole fraction, mass % and ppm of NaOH in this solution. (You will need the density of water.) Consider a 0.300 M solution of NaOH? Calculate the molality of NaOH. (Assume the density of the solution is the same as the density of pure water.)

Density is defined as the mass per unit volume. Dissolved salts and changes in temperature alter the density of a water sample. Freshwater is less dense than saltwater at a given temperature. Density of pure water increases with decreasing temperature until about 4 ºC, at which point the density …

The density increases with either a temperature decrease or a salinity increase. Under normal ocean conditions, temperature fluctuations exert a greater influence on seawater density because the range of marine temperatures values is much greater (-2( C to 30( C) than the range of open-ocean salinity.
