5. You will also make other concentrations of solutions. If the concentration is to be less than a mole, reduce the mass of the substance accordingly. If the concentration is to be greater than 1M, increase BIOL 1406 the mass added or reduce the volume of water accordingly. Use this formula: Molarity = moles/liter. Example: Make a .5M solution of HCI Name: H = 1.008 Daltons CI = 35.45 Daltons Total = 36.46 Daltons = 36.46 grams .5M = X moles/1 liter .5M * 1 liter = X moles Date Number of moles = .5 .5 * 36.46 = 18.23 grams Add 500 mLs water to 1L volumetric flask, add the 18.23 grams HCI to the water, swirl to dissolve, then add water until it reaches the 1L or 1,000 mL mark.

Suppose you are working with a NaOH stock solution but you need a solution with a lower concentration for your experiment. Calculate the volume (in mL) of the 1.100 M stock NaOH solution needed to prepare 250.0 mL of 0.1230 M dilute NaOH solution.

A student weighs out a 2.76 g sample of NaOH , transfers it to a 500. mL volumetric flask, adds enough water to dissolve it and then adds water to the 500. mL tick mark. What is the molarity of sodium hydroxide in the resulting solution? Molarity =  _____M

So, I don't understand how to calculate concentration for solutions that have been diluted twice. You have W mL of a solution with concentration M. You dilute it to a final volume of X mL.You then pour it out until you're left with Y mL of that diluted solution. Then you dilute what's left to a final volume of Z mL.What's the formula for the final concentration of the solution?
