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

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
