The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 10-4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 3.6 atm. Assume that the total volume of blood in the body is 5.0 L. Calculate the amount of N2 gas released (in liters at 37°C and 1.4 atm) when the diver returns to the surface of the water, where the partial pressure of N2 is 0.80 atm.
Calculate the relative proportions of two conformers A and B in a compound, assuming that an energy of 15.5 kj/mol is required
If the acid dissociation constant, Ksuba, for an acid HA is 8 x 10^-4 at 25 degree C, what percent of the acid is dissociated in a 0.50 M solution of HA at 25 degree C?
One liter of a gas has a pressure of 150.00 kPa at 25.0°C. If the pressure increases to 600.0 kPa and the temperature to 100.0°C, what would be the new volume of the gas?
we determined that the sample contained 5.34mol of oxygen. If all of this oxygen were converted to a gas at 24 degrees celcius and 770mmHg of pressure, what volume would it occupy?
