Answer:
The answer to your question is M
Explanation:
Concentration is represented in a lot of units like Molarity, molality, normality, mass percent, etc.
These units consider the moles or grams of the solute and the volume of the solvent.
Molarity measures the number of moles of solute per liter of solvent and is represented with a letter M (uppercase).
Answer: For a given mass and volume, how much physical space a material takes up, of an object or substance, the density remains constant at a given temperature and pressure. The equation for this relationship is ρ = m / V in which ρ (rho) is density, m is mass and V is volume, making the density unit kg/m3.
