What is the molar concentration (molarity) of nonelectrolyte solutes in the human body if the osmotic pressure of human blood is 7.53 atm at 37°C? R = 0.0821 (L.atm) / (mol.K)
For the reaction, N2 (g) + 3 H2 (g) → 2 NH3 (g), the change in the standard free energy is – 33.32 J/mol.
At 298 K, what is the value of K for this reaction?

Decompression sickness, also known as “the bends”, occurs when the human body goes from a region of high pressure to low pressure too quickly, releasing dissolved gases (mostly nitrogen) from the bloodstream as bubbles inside the body, similarly to opening a can or bottle of pop. Examples of when the bends can occur when ascending too quickly from a scuba dive or leaving a hyperbaric chamber back to atmospheric pressure. Symptoms are varied, but may include neurological damage, joint and...
