QUESTION 5 Hydrogen is in a 5.00L container at a pressure of 6.875atm. Oxygen is in a 7.50L container at 2.13atm. The valve between the bulbs is opened and then a spark ignites the mixture causing a reaction. The temperature is high enough that the water formed remains a gas. What is the partial pressure (in atm) of the oxygen in the combined system prior to reacting with hydrogen? (Use three sig figs, do not include units)

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.
