During the standardization procedure of the iodine dropper, a student used 10.0 mL of a 1.00 mg.mL standard of Vitamin C. After adding 41 drops of iodine to the 10.0 mL of the standard, the sample was a deep blue. Calculate how many mg of Vitamin C are titrated by each drop of iodine (mg VC/dp l2), from this dropper bottle. The # of drops is an exact #, so it's not taken into consideration when determining the # of sig figs in the calculation. Please show work.

To calculate the number of milligrams (mg) of vitamin C titrated by each drop (dp l2) of iodine, we first need to determine the amount of iodine used in the titration.

Given:
Volume of iodine used: 41 drops
Concentration of vitamin C standard: 1.00 mg/mL
Volume of vitamin C standard used: 10.0 mL

Step 1: Calculate the total amount of vitamin C in the sample.
Total amount of vitamin C = Concentration of vitamin C standard × Volume of vitamin C standard used
Total amount of vitamin C = 1.00 mg/mL × 10.0 mL

Step 2: Convert the volume of iodine used to milliliters (mL).
According to the information provided, the volume of iodine used is an exact number and does not need to be taken into consideration for significant figures.

1 drop ≈ 0.05 mL (approximation)

Using the above approximation, we can calculate the volume of iodine used:
Volume of iodine used = 41 drops × 0.05 mL/drop

Step 3: Calculate the concentration of iodine based on the volume used.
Concentration of iodine = Total amount of vitamin C / Volume of iodine used

Step 4: Calculate the amount of vitamin C titrated per drop of iodine.
The amount of vitamin C titrated per drop = Concentration of iodine

Let's plug in the values and calculate:

Total amount of vitamin C = 1.00 mg/mL × 10.0 mL = 10.00 mg

Volume of iodine used = 41 drops × 0.05 mL/drop = 2.05 mL

Concentration of iodine = Total amount of vitamin C / Volume of iodine used = 10.00 mg / 2.05 mL
Concentration of iodine = 4.8780 mg/mL (rounded to four significant figures)

Therefore, each drop of iodine titrates approximately 4.88 mg of vitamin C (mg VC/dp l2).

To calculate the number of milligrams of Vitamin C (VC) titrated by each drop of iodine in this scenario, we need to follow these steps:

Step 1: Calculate the total number of milligrams of Vitamin C in the 10.0 mL sample.
Given that the concentration of the standard Vitamin C solution is 1.00 mg/mL, we can use the formula:
total VC = volume × concentration
total VC = 10.0 mL × 1.00 mg/mL
total VC = 10.0 mg

Step 2: Calculate the number of milligrams of Vitamin C per drop of iodine.
To determine this value, we need the total number of drops of iodine used in the titration. The question mentions that 41 drops were added to the 10.0 mL sample.

Therefore, we divide the total amount of Vitamin C (10.0 mg) by the number of drops of iodine (41 drops) to find out how many milligrams of VC correspond to each drop of iodine:
mg VC/drop l2 = total VC / number of drops
mg VC/drop l2 = 10.0 mg / 41 drops

Now, we can calculate the value:
mg VC/drop l2 = 0.2439 mg/drop

Therefore, each drop of iodine titrates approximately 0.2439 milligrams of Vitamin C.
