Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 55.0 gallons and which contains O2 gas at a pressure of 16,500 kPa at 21 ∘C. What mass of O2 does the tank contain? What volume would the gas occupy at STP? At what temperature would the pressure in the tank equal 160.0 atm? What would be the pressure of the gas, in kPa, if it were transferred to a container at 24 ∘C whose volume is 55.0 L?

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.
