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.

For ideal gases with each of the following sets of P, V, n, and T, determine the missing number. Note that these different sets of numbers are not related to one another. Pay attention to the units. PS: Make sure that you have rearranged the equation properly. If you start from the PV=nRT form of the equation, you should never have to do anything other than dividing to isolate the variable of interest. Also, make sure you are using the proper value of R. To do so, make sure the units line up with the data that is given in the question.
