Asked by Sarah

Assuming that sea water is a 3.5 wt% solution of NaCl in water, calculate its osmotic pressure at 20 deg C. The density of a 3.5% naCl solution at 20 deg C is 1.023 g/mL.

How do I go about solving this?

pi = MRT where pi is the osmotic pressure, M is the molarity, R = 0.08205 and T is in Kelvin. Use the density to calculate molarity.
