What is the amount of solute per given amount of solvent?

1.) dilution
2.) solubility
3.) saturation
4.) concentration

2. solubility

Explanation:

Solubility is the amount of a substance (solute) that dissolves in a unit volume of a liquid substance (solvent) in order to form a saturated solution under certain aspects of temperature and pressure.

the answer would be a

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
