You have a container filled with 12 moles of neutral lithium. how much negative electric charge is contained in the electrons of all the lithium atoms in the container

3469248 C

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by .

Avogadro constant:-

Thus, number of atoms of lithium in 12 moles =

Also, 1 atom of lithium has 3 electrons.

So, number of electrons in 12 moles of lithium atoms =

Charge on 1 electron =

So,

Total negative charge = = 3469248 C

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
