Question

A student finds that 37.80 mL of a 0.4052 M NaHCO34324 22

  1. solution is required to titrate a 20.00 mL sample of sulfuric acid solution. What is the molarity of the acid? The reaction equation is H2SO + 2 NaHCO --> NaSo+ 2 HO + 2 CO.
  2. The Henry's law constant for nitrogen in blood serum is approximately 8 x 10-7 mol L-1 mm Hg-1. Calculate the N2 concentration in a diver's blood at a depth where the total pressure is 2.5 atm. The air the diver is breathing is 78% N2 by volume.
  3. The partial pressure of O2 in your lungs varies from 25 mm Hg to 40 mm Hg. Calculate the concentration of O2 (in grams per liter) that can dissolve the water at 37°C when the O2 partial pressure is 40 mm Hg. The Henry's law constant for O2 at 37°C is 1.5 x 10-6 mol L-1 mm Hg-1.
  4. Calculate the freezing point of a solution of 2.12 g of naphthalene, C10H8, in 32.0 g benzene, C6H6. Pure benzene freezes at 5.50°C and its Kf = 5.10°C/m.
  5. Distinguish precisely, and in scientific terms, the differences among items in each of the following pairs or groups.

(a.) Solute, Solvent (b) Concentrated, dilute (c) Saturated, unsaturated, supersaturated (d) Soluble, miscible

6.Does percentage concentration by mass of a solution depend on temperature?

7.If you know either the percentage concentration of a solution or its molarity, what additional information must u have before u can convert to the other concentration?


PLEASE IF YOU PUT IT IN A PAPER, PLEASE WRITE IT CLEARLY BECAUSE MY EYES ARE DAMAGED AND I CANT CLEARLY SEE. THANK YOU.

11. The vapor pressure of ethanol, C2 H,OH, at 50.0 C is 233 mm Hg, and its normal boiling point at 1 atm is 78.3 C. Calculate the A Hvap of ethanol.

19. In this phase diagram, make these identifications: 5. B Pressure (atm) Temperature (C) a) What phase is present in region A? Region B? Region C? b) What phases are in equilibrium at point 1? Point 2? Point 3? Point 5?
