Calculate the osmotic pressure at 25°C across a semipermeable membrane separating seawater (1.14 M total particles) from a 0.503 M solution of aqueous NaCl.

The osmotic pressure is 24.6 atm

Explanation:

π = M . R . T . i → Formula for osmotic pressure

i = 2 ⇒  NaCl →  Na⁺ + Cl⁻

i means Van't Hoff factor, which indicates the numbers of ions dissolved, by the stoichiometry.

R → Universal gases constant

T→ T° in K → T°C + 273 → 25°C + 273 = 298K

π = Osmotic pressure

Let's replace data given ⇒ π = 0.503 mol/L . 0.082L.atm/mol.K . 298K .2

π = 24.6 atm

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
