3. Calculate the molarity of acetic acid in the diluted vinegar sample using the calculated moles of HC,H,O, in the 15.00 mL diluted vinegar sample. Remember to find molarity the volume must be in liters. (Show work below) M of HC,H,O2 in diluted vinegar sample 4. Giye the molarity of acetic acid in the vinegar before it was diluted. The original vinegar

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. Answer the following questions: 1. How many mL should I use to make a 1M solution of MgBr2? ¶ 2. What is the mass of a mole of NH3? 3. How much CaCO3 should I use to make a 2M solution? 4. How much CaCO3 should I use to make a .25M solution? 5. What are the steps to make a 1M solution of NH3 - give the steps and…

2. How would each of the following affect your calculated molarity (too high, too low, or no effect). Explain your answers. a) The balance wasn’t zeroed with the beaker, and the beaker’s mass was included in the measurements. b) Not all of the baking soda in the final scoop that was counted actually reacted. c) The baking soda used isn’t pure sodium carbonate.
