Question

1) Calculate the m olality of each of the following aqueous solutions: (a) 0.940 M KBr solution (density of solution 1.08 g/mL), (b) 29.2 percent by mass NaCl solution, (c) 14.3 g of sucrose (C12H20n) in 676 g of water. 2) The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 x 104 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 4.5 atm. Calculate the number of moles of N2 are in the blood of the diver when breathing at this level in the deep-sea. Assume that the total volume of blood in the body is 5.0 L Please can you solve 1 &2 ASAP. Thank you.

    Henry’s law states that the solubility of a gas is directly proportional to the partial pressure of the gas if the temperature is constant. Hyperbaric chambers, which provide high pressures (up to 6 atm) of either air or pure oxygen, are used to treat a variety of conditions, ranging from decompression sickness in deep-sea divers to carbon monoxide poisoning. Look up the Henry’s Law Constant (kH) for N2, O2, and CO2 in the textbook. a) Calculate the solubility (concentration in...
