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 are clearly written and easy to follow. Task 2: For each step show the corresponding calculation including equations where appropriate. You can choose any of the experimental results from the 5 drinks below to show your calculations.
|
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 are clearly written and easy to follow.
Task 2: For each step show the corresponding calculation including equations where appropriate.
You can choose any of the experimental results from the 5 drinks below to show your calculations.
- ONLY calculations for ONE drink are required. (Pick your favourite drink # from the table? )
- Remember to include the drink number you chose as a reference on your portfolio.

*Provide your final answer with 2 decimal places.
Task 3: Using https://www.foodstandards.gov.au/consumer/nutrition/Pages/Sugar.aspx how would you rate the drink you chose when compared to the daily WHO recommended “free sugar” intake? Will consuming 1 L of this drink bring a healthy individual close to or over their daily recommended “free sugar” intake or will it not make much difference?
Examples on how you could show your steps:
Step 1: convert from ….. to ……
X unit × Y = …… unit
Step 2: divide by …… to obtain …..
