We're being asked to calculate the milliliters of N2 gas released into the blood stream.
For this problem, we will do the following steps:
Step 1: Calculate Henry’s Law constant for the gas
Recall that the solubility of a gas is given by Henry’s law:
Sgas = solubility of the gas (in mol/L or M)
kH = Henry’s law constant for the gas
Pgas = partial pressure of the gas
At ordinary body temperature (37 oC), the solubility of N2 in water at ordinary atmospheric pressure (1.0 atm) is 0.015 g/L. Air is approximately 78 mol % N2.
At a depth of 100 ft in water, the external pressure is 4.0 atm. If a scuba diver suddenly surfaces from this depth, how many milliliters of N2 gas, in the form of tiny bubbles, are released into the bloodstream from each liter of blood?
