Explanation:
As a neutral lithium atom contains 3 protons and its elemental charge is given as . Hence, we will calculate its number of moles as follows.
Moles =
=
= 100 mol
According to mole concept, there are atoms present in 1 mole. So, in 100 mol we will calculate the number of atoms as follows.
No. of atoms =
= atoms
Since, it is given that charge on 1 atom is as follows.
=
Therefore, charge present on atoms will be calculated as follows.
Thus, we can conclude that a positive charge of is in 0.7 kg of lithium.
