Seawater contains 3.4 g of salts for every liter of solution. Assuming that the solute consists entirely of NaCl (in fact, over 90% of the salt is indeed NaCl), calculate the osmotic pressure of seawater at 20 °C.

The specific gravity of seawater is 1.025, not the usual 1.00 for water, and is 3.5% salt (mostly NaCl) by mass. This increased density is due primarily to the dissolved NaCl in the seawater. Give the density (kg/m3) of the seawater, and then the molarity, molality, ppm (per mass), mole fraction, and TDS of the NaCl in the water, as if it were the only dissolved component. We did not discuss TDS in class, because I want you to find its meaning through a quick search. answers: r = 1025 kg/m3, conc = 0.614 M, 0.621 m, 35,000 ppm, x = 0.0110, TDS 35,900 mg/L.

Assume seawater is a solution of 0.570 M NaCl. Calculate the minimum pressure required at 10.00°C to desalinate seawater so that it contains no more than 173 mg NaCl per liter.
