The molecular formula of the compound that we are required to find is the compound C4H8O8

<h3>What is empirical formula?</h3>

The empirical formula of a compound is a formula that shows the ratio of each atom present in the compound. We will start by dividing each mass with the relative atomic mass of the atom.

Carbon -  48.38 g/12   Hydrogen - 6.74 g/1    Oxygen -  53.5 g/16

Carbon - 4                    Hydrogen - 6.74         Oxygen -  8.9

Dividing through by the lowest ratio;

Carbon - 4/4            Hydrogen -  6.74/4           Oxygen 8.9/4

Carbon   1               Hydrogen    2                     Oxygen  2

The empirical formula is CH2O2.

To obtain the molecular formula; brainly.com/question/11588623

n = 180/[12 + 2 + 32]

n =4
