Answer:
Intermolecular forces: forces attracting one molecule to its neighbors.
Explanation:
Hello,
Bonds are formed when two molecules are interacting (crashing or attracting to each other) and they are allowed to get joined via their valence electrons since we're talking about bonds. Those forces are called intermolecular forces as long as the molecules have charges that could attract or repeal another molecule (neighbors), of course, as we're considering bonds, we talk about attractive forces, making the bonding to be effective.

Atomic mass of Potassium = Mass of 1 atom of Potassium = 39.1 amu
Then
Mass of 6.02 x 1023 atoms of potassium = 39.1 x 6.02 x 1023 amu
=
We already know that
1 mole = 6.02 x 1023 atoms
Also
Number of mole = mass in grams/ atomic mass
Then
Mass in gram = Number of mole x atomic mass
= (39.1 x 6.02 x 1023)/(6.02 x 1023)
= 39.1 g
The correct option among all the options that are given in the question is the third option or option "B".
Oxygen is a pure substance, as it is composed of only a single kind of atom. Which is the oxygen atom, it cannot be broken or degraded down any further into constituents that make up the element. In terms of both chemically and physically.
