Which of the following expressions is equivalent to molarity [M]?
a. [M] = moles of solute volume of solution in liters
b. [M] = grams of solute volume of solution in liters
c. [M] = moles of solute volume of solution in gallons
d. [M] = volume of solution in liters moles of solute
Molarity is the number of moles of solute dissolved in one liter of solution. It is also calculated with the following equation: M (mol/L)= n (mol)/ V (L) Thus a is the best answer. Hope this would help :))
