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.

Question

Assume that the molar mass of A is 82.93 grams per mole and the molar mass of E is 24.61 grams
per mole.
Consider the compound A,E7. What is the mass percent of E in the compound? Report your
answer to two decimal places (ignore significant figures).
