A compound has a molar mass of 92.09g/mol. Its percent composition is: 39.12% C, 8.75% H, and 51.12% O. What
is the molecular formula?
A. C2H302
B. CH2O
C. C2H4O2
D. C3H2O3

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

elements make up everything, and they combine to make compounds.

the answer is c

answer: mole of the gas

answer: mole of the gasexplanation:
