In a universe far, far away, there exists an alien world where they have a different periodic table, as shown below. Elements behave just like they do here, there are just less of them, and they have different names. You can calculate molar mass and other things from this periodic table just like you would from the periodic table on our world.

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.
