Answer to Question #277310 in General Chemistry for Bela

Question

Discovering the deepest seas requires professional deep-sea divers to use special tanks with Heliox- a diving gas mix that may have a typically less of oxygen as regular air but completely replaces the nitrogen with helium for their safety and support underwater. If a diver travels 150 meters below sea level, they may experience the weight of around 10 atm. Their 10-liter tanks contain 55.3 g of O2 and 330.6 g of He as trace gases. As they descend into the sea floor, what would be the partial pressure of oxygen and helium and the total pressure in the container at a temperature of 18 ◦C? 

Answer 1

Total pressure =5.216atm
