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: Mass of water produced is 17.3 grams
Explanation:
To calculate the number of moles, we use the equation:
.....(1)
For benzene:
Given mass of benzene = 25.0 g
Molar mass of benzene= 78 g/mol
Putting values in equation 1, we get:
The chemical equation for the reaction follows:
As, oxygen is an excess reagent. Thus benzene is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
2 moles of benzene produces 6 moles of water
So, 0.32 moles of benzene will produce = of water
Now, calculating the mass of water from equation 1, we get:
Molar mass of water= 18 g/mol
Moles of water = 0.96moles
Putting values in equation 1, we get:
Thus mass of water produced is 17.3 grams
