Answer: Concentration

Explanation: Concentration is the amount of a solute that is contained in a given volume of a solution.

Dilution is the addition of solvent to a solution to make the solution less concentrated.

Molarity is the number of moles of a solute per litre of a solution. It is the concentration of a solute in a given volume of a solution.

A solvent is a substance in which other substances dissolve to form a solution.

The p subshell can hold up to eight electrons in an atom (2 points)<br> True or false?
hoa [83]

Answer: The statement is false

Explanation:

Electrons occupy a region in atoms known as orbitals or subs hell.  These orbitals include

I) S-orbital: it can occupy a maximum of two electrons

II) P-orbital: It occupies a maximum of six electrons

III) D-orbital: it occupies a maximum of ten electrons

F and G-orbitals as examples of other orbitals present.

A good illustration of the 6 electrons occupied by the P-subshell is seen in Sodium (Na) with atomic number of 11

Na = 1s2, 2S2 2p6, 3s1

Note: extra electrons are transferred to the next orbital
