Molarity tells us ___.

A. whether a solution is considered weak or strong

B. how many grams of solute are dissolved in a given volume of solution

C. the likelihood that a given volume of solution will dissolve more solid

D. how many particles are dissolved in a given volume of solution

The answer is

B. how many grams of solute are dissolved in a given volume of solution.

Explanation:

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution

M=n/v

M-molar concentration

N-moles of solute

v-liters of solution

To find the molar concentration of a solution, simply divide the total moles of solute by the total volume of the solution in liters.

Molar concentration is the same as molarity, but molarity and molality are not the same thing. They are different ways to quantify the amount of solute in a solution, and the concentration of a solution in molarity is not interchangeable with its concentration in molality.
