Option C

Explanation:

Molarity → It is the sort of concentration that indicates the moles of solute in 1 liter of solution.

Units of molarity are mol/L, and it can also be represented as M

If we begin with the mass of solute in grams, we must convert it to moles

(mass / molar mass of the solute) and afterwards, we divide by the volume of solution, in L.

That's the value of M

The right step is C.
