Hi I need help with my chemistry problem. You have 50 ml of a drink with 100 mg/liter of vitamin c. How many ml of iodine solution (5% w/v) do you need to react with the vitamin c in the sample? Thank you so much for your help Karen
1 Answer
You need 140 mL of the iodine solution.
Explanation:
Step 1, Calculate the mass of Vitamin C
Step 2, Calculate the moles of Vitamin C
Step 3, Calculate the moles of
The equation for the reaction is
Step 3, Calculate the mass of
Step 4, Calculate the volume of
Note: The answer can have only one significant figure because that is all you gave for the concentration of the iodine solution.
However, I calculated the volume to two significant figures.
