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.

Remember that % is the symbol for percent or parts per hundred -- divide % by ten or add another zero in the denominator and you have parts per thousand. Thus, a salinity value of 35 o /oo means 35 parts of dissolved salt per 1,000 parts of sea water. Similarly, a sodium (Na +) concentration of 10 o /oo means 10 pounds of sodium per 1,000 pounds of water. The salinity of sea water exhibits a variation around an average value of 35.5 o /oo in the world's oceans depending on the balance between evaporation (increasing salinity) and precipitation (decreasing salinity).
