Acting  in drama, pretending to be someone else, usually through a combination of line delivery, costumes, props, and how the actor presents him or herself.
Ocean water typically contains 35 moles of salt ions dissolved in each 1000 moles of water. Assuming that ocean water has the same density as pure water convert this ratio into a molarity and calculate the expected osmotic pressure of ocean water.cean water typically contains 35 moles of salt ions dissolved in each 1000 moles of water.

Changes in ocean water density with depth at different latitudes. Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 599 mM), which is a specific gravity of about 1.025.This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+) and chloride (Clâ) ions).he density of surface seawater ranges from about 1020 to 1029 kg/m 3, depending on the temperature and salinity. Deep in the ocean, under high pressure, seawater can reach a density of 1050 kg/m 3 or higher.
