Obviously, Solution #1 is a pure water that has . no. molarity of blue dye (0 Moles/Liter). Solution #8 is . pure. Blue Dye and so it has a concentration of 1 M. To determine the others, you need to use the formula: M1V1 = M2V2. M1 = molarity of stock solution (always. 1 M in each solution. That’s the stock molarity) V1 = Volume amount (mL ...

Molarity is a measures of concentration, as it relates the mass of the solutes to the volume of the solution. - It is calculated by first determining the number of moles of solute in a solution, and then dividing by . the volume (in liters) of the solution. Example: Find the molarity of a solution containing 70.70 grams of CaCl2 in 750 mls.
