Answer:
Carbon has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
Boron has 5 protons, 5 electrons and 6 neutrons for the most common isotope. This determines that it has a neutral charge.
When an atom has an equal number of electrons and protons it has an equal number of negative charge (the electrons) and positive electric charges (the protons). The total electric charge of the atomic is therefore zero

Answer:
If you want to calculate the number of moles of any compund, you should look for the molar mass. For LiF, its molar mass is 25,9 g/m So if 25,9 g are in one mol, the 317 in how many?. Then 12,2 is the number of moles of lithium fluoride produced.
Explanation:
To get the molar mass of a compound, you should know the mass at the Periodic Table, for Li 7,00 , for F 18,9
