Seawater has a salinity of 3.5%, i. e. 35 g of solid nacl for one kilogram of seawater. for simplicity, assuming that all dissolved salts in seawater are nacl rather than na and cl- ions and other species, what is the osmotic pressure between seawater and fresh water at 300k?

π = 29.3 atm

Explanation:

The osmotic pressure π is given by

π = i MRT, where i=Vant Hoff factor =2 for NaCl ( 2 moles ions/mol NacL)

                            M = molarity

                            R = 0.0821 Latm/molK

                            T = temperature K

Assuming density of solution is 1 g/mL

M= 35 g/58.44 gmol / 1 L =  0.60 M

π = 2.0 x 0.60 mol/L x 0.0821 Latm/kmol x 300K = 29.3 atm

58750.08068 is the answer i think

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
