Scuba divers who suffer from decompression sickness are treated in hyperbaric chambers using a gas mixture called "Heliox" (21% oxygen and 79% helium), at a pressure of 120 psi. If the partial pressure of helium is 6.45 atm at 25 degrees Celsius in a 155 L chamber, calculate the partial pressure of O2 (in atm) in the hyperbaric chamber under these conditions and how many grams of oxygen are in the chamber.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
