To determine the correct formula for calculating molarity, let's carefully evaluate the options presented:

Molarity (M) is defined as the number of moles of solute divided by the volume of the solution in liters. This definition guides us to find the appropriate formula among the given options.

Let's examine each choice:

a. Moles of solute (mol) x liters of solution (L)
This option suggests multiplying moles of solute by liters of solution, which does not align with the definition of molarity. Hence, this is incorrect.

b. Moles of solute (mol) / liters of solution (L)
This option correctly suggests dividing the moles of solute by the liters of solution, which matches the definition of molarity. This is the correct formula.

c. Moles of solute (mol) + liters of solution (L)
This option suggests adding moles of solute to liters of solution, which is not consistent with the definition of molarity. Therefore, this is incorrect.

d. Moles of solute (mol) - liters of solution (L)
This option suggests subtracting liters of solution from moles of solute, which also does not fit the definition of molarity. Thus, this is incorrect.

Based on these evaluations, the correct formula for calculating molarity is:
b. Moles of solute (mol) / liters of solution (L)
