Three elements, A, Q, and Z, have the molar masses indicated in the table below. Given a compound with a composition of 42.6% A and 57.4% Z by mass, what is the empirical formula of this compound? Remember to enter subscripts as normal numbers (ie H2O is entered as H2O) and to enter elements in the same order they were given.

Explaination:
Step 1:
Instantaneous Dipole: As the pentane molecule is non polar in nature and the electron density on each molecule is symmetrical. When this symmetrical molecule approaches second symmetrical molecule there disturbance is caused due to repulsion between electrons. Due to repulsion the electrons changes there position and for a small period of time an instantaneous dipole is produced on pentane molecule.
Step 2:
Induced Dipole: The dipole produced in step one when approaches another symmetrical pentane molecule, the partial positive part (low electron density site) attracts the electron from symmetrical pentane and induces polarity in it.
In this way the process repeats and interactions are developed between the non polar pentane molecules.
