Answer: The empirical formula of the compound becomes
<u>Explanation:</u>
The empirical formula is the chemical formula of the simplest ratio of the number of atoms of each element present in a compound.
We are given:
Mass of C = 48.38 g
Mass of H = 6.74 g
Mass of O = 53.5 g
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
To formulate the empirical formula, we need to follow some steps:
- <u>Step 1:</u> Converting the given masses into moles.
Molar mass of C = 12 g/mol
Molar mass of H = 1 g/mol
Molar mass of O = 16 g/mol
Putting values in equation 1, we get:
- <u>Step 2:</u> Calculating the mole ratio of the given elements.
Calculating the mole fraction of each element by dividing the calculated moles by the least calculated number of moles that is 3.023 moles
- <u>Step 3:</u> Taking the mole ratio as their subscripts.
The ratio of C : H : O = 1 : 2 : 1
Hence, the empirical formula of the compound becomes

BIOSPHERE AND LITHOSPHERE INTERACTION
The quantum model is regarded as the most current model to explain the composition of an atom. The Bohr model and the quantum model are fundamentally different in that the former explains the particle behavior of an electron while the latter explains its dual nature as a wave and a particle.
<h3>
What is the Bohr Model?</h3>
The Bohr model of the atom was put forth by Neil Bohr in 1915. It was developed by altering Rutherford's atomic model. Rutherford demonstrated how a positively charged nucleus is surrounded by negatively charged electrons in his nuclear model of an atom.
The Bohr hypothesis modified the atomic structure model by explaining that electrons move in fixed orbitals (shells) and not anywhere in between. He also demonstrated the fixed energy of each orbit (shell). Bohr added electrons and their many energy levels to Rutherford's revised concept of the atom's nucleus.
In Bohr's theory, there is a tiny, positively charged nucleus that is surrounded by negatively charged electrons that orbit the nucleus. According to Bohr, an electron that is farther from the nucleus has more energy than an electron that is closer to the nucleus.
