The electron dot diagram for the oxygen atom shows six electrons around the symbol of the atom.
<h3>What is the electron dot diagram?</h3>The electron dot diagram is the diagram of atoms of elements showing only the valence electrons present in the atom represented with dots.
The electron dot diagram for the oxygen atom is drawn as follows:
- The number of valence electrons in oxygen atom is determined; valence electrons = 6
- The symbol for the oxygen atom is written
- The valence electrons are shown as dots around the symbol of the element.
In conclusion, the electron dot diagram uses dots around the symbol of an atom to show the valence electrons in the atom.

Answer : The mole fraction and partial pressure of and
gases are, 0.267, 0.179, 0.554 and 1.54, 1.03 and 3.20 atm respectively.
Explanation : Given,
Moles of = 1.79 mole
Moles of = 1.20 mole
Moles of = 3.71 mole
Now we have to calculate the mole fraction of and
gases.
and,
and,
Thus, the mole fraction of and
gases are, 0.267, 0.179 and 0.554 respectively.
Now we have to calculate the partial pressure of and
gases.
According to the Raoult's law,
where,
= partial pressure of gas
= total pressure of gas = 5.78 atm
= mole fraction of gas
and,
and,
Thus, the partial pressure of and
gases are, 1.54, 1.03 and 3.20 atm respectively.
