Rutherford postulated the existence of some neutral particle having mass similar to proton but there was no direct experimental evidence. Several theories and experimental observations eventually led the discovery of neutron.
Mass = mole x molar mass
Explanation:
The mole of the substance used in the bakanced eqn multipled by its molar mass equals to Its mass
The molecules of Li₂O that would produce if you used up 6 atoms of Li(s) is 3.
<h3>What is Lithiumdioxide?</h3>
It is an unstable inorganic and radical compound, used in the manufacture of glass and ceramic.
The balanced equation

If the atoms of lithium moves up to 6 the lithium oxide molecules will be 3, as you can see in the equation.
Thus, the molecules of Li will be 3.
