- Drink # Glucose Concentration in mM 1 2.455 mM 2 0.307 mM 3 3.750 mM 4 1.100 mM 5 1.500 mM From here, each group needs to convert the concentration of their drink from mM of the diluted drink into g/100mL of the undiluted drink. This is where you come in! The students are stuck at this point and really need your help! Main Goal: Convert the experimental glucose concentration (provided in the table below) from mM (millimolar) to g/100 mL. Hints & Tips Take the 1/100 dilution factor into consideration Molarity will open the doors for you to get to grams. Once at M assume 1L of solution. (Hint: this will help you when converting from M to moles) You will also need to calculate the molar mass of glucose which has the formula C6H12O6 There are 5 steps in total Task 1: Write a step-by-step guide with key words for the Chem 2 students on how to do these calculations. You can use diagrams, a table or just type the steps out. Ensure the steps…A buret is used to measure the volume of FeCl3 aqueous solution. The starting volume is recorded to be 5.28 mL.

You have previously determined an experimental conversion factor of 0.26 mg ascorbic acid/mL dye using an ascorbic acid standard. After measuring out 5.16 mL of your orange juice sample and ~10 mL of 3% metaphosphoric acid to a graduated cylinder, you dilute the solution to 50.33 mL with DI water. You finally dispense 10.87 mL of the diluted solution into an Erlenmeyer flask, add 4 drops of HCl, and use 6.48 mL of dye to reach the equilibration point. How much ascorbic acid (mg) is in your concentrated orange juice sample? The molecular weight of ascorbic acid is 176.12 g/mol.Question 4. You are on a field trip with your professor and he asks you to make a fixative solution to collect and preserve specimen. You are told to prepare 200 mL of fixative solution containing 30% formaldehyde (vol/vol), 1X glycerol and 2.5 mM sodium chloride (NaCI). In the field trip van you find a stock of 100% pure formaldehyde (liquid), a 10X glycerol stock (liquid), plenty of water and a stock solution of 5M NaCl. There are also all kinds of pipets, cylinders and beakers to measure volumes. 1. a) provide calculations and describe the process of making the fixative solution?
