How many grams are in 3.00 mol of sodium chloride (nacl)?

175.05 grams

Explanation:

A mol is the molecular unity that a certain compound has, in order to calculate that we first need to know both molar masses of the two elements. for Sodium would be: 22.90 grams, and the molar mass for Chlorine is: 35.45.

We need to add both to know the sodium chloride molar mass:

22.90+35.45=58.35

So the molar mass of NaCl is 58.35 grams per mol.

Now we just have to multiply that by 3 which is the number of mol and we get how many grams are in 3 mol of sodium:

58.35x3=175.05 grams

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
