Osmotic pressure π is given by the relation: π = imrtwhere i is the van’t hoff factor, m is the concentration of solute, r is the gas constant, and t is the temperature. the osmotic pressure of sea water is approximately 24 atm at 25°c. what is the approximate concentration of salt in sea water (approximated by nacl with i = 2)? (note: use r = 0.08 l•atm/mol•k.)

The concentration of solute is 0.503 mol/L

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

where,

= osmotic pressure of the solution = 24 atm

i = Van't hoff factor = 2 (for NaCl)

c = concentration of solute = ?

R = Gas constant =

T = temperature of the solution =

Putting values in above equation, we get:

Hence, the concentration of solute is 0.503 mol/L
