Answer to Question #187075 in General Chemistry for Catherine

Question

Seawater contains dissolved salts at a total ionic concentration of about 1.13 mol/L. Determine the pressure, in atm, needed to prevent the osmotic flow of pure water into seawater through a membrane permeable only to water molecules. Round your answer to three (3) significant figures. Omit the unit in your final answer.

Answer 1

P = mrt

= 1.13 × 273 × 8.31

= 2563.5519/1000

= 2.56 atm
