6)The equation for molarity states that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. In the first equation, the molarity will clearly be equal to 1.0 M, because there are 1.0 moles of NaCl and a solution volume of 1.0 L.

4. "Serial dilution" - This term is frequently used and refers to a "multiple" dilution problem. In other words, an initial dilution is made and then this dilution is used to make a second dilution, and so on. For example, a 1:2 serial dilution is made using a 1 mL volume of serum.

Apr 24, 2006 · Molarity. Molarity (M) is the number of moles of solute dissolved in one liter of solution. Calculating molarity: Divide moles of solute by the volume of solution. Molarity (M) = moles of solute. liters of solution. Volume is the total volume of solution not the volume of the solvent alone. Molarity. 3 M NaCl = 3 molar solution of salt. Practice:

Calculating Molarity: Before you take measurements using the spectrophotometer, you need to calculate the molarity for the original sample, as well as for each dilution. Proceed as indicated below: Original sample: 0.0400 moles C12H22O11 Volume = 100.0 mL. Molarity = _____ Dilution (20.0 mL / 250.0 mL) M1 = V1 = V2 =
