Problem- Sea water consists of an aqueous solution of the following cationic and anionic species: Na+ (0.479 M), Mg2+ (0.109 M), Ca2+ (0.021 M), K+ (0.010 M), Cl- (0.560 M), SO 2- 4 (0.057 M), and HCO - (0.0020 M). The ionic content of sea water is 3.50% by mass. The 3 temperature is T = 25.0°C.
(a) What is the osmotic pressure exerted by sea water on a semi-permeable membrane that separates the sea water from pure water?
(b) If the vapor pressure of pure water at room temperature is 0.0313 atm, then is the vapor pressure of sea water higher or lower than that of pure water? Quantify your answer by determining the difference between the two vapor pressures. One liter of water has a mass of one kilogram.
I want you to explicate the chemistry in this problem
What is the density of a sample of air (average molar mass is 28.8 g/mol) that has a pressure of 750torr and a temperature of 27 degrees C?
Aqueous solutions of 30% (by weight) hydrogen peroxide, H2O2, are used to oxidize metals or organic molecules in chemicals reactions. Given that the density of the solution is 1.11 g/mL, calculate the molality, molarity, and mole fraction.
