Question

An iodine/vitamin C titration was performed similar to Lab 3. It was found a tablet contained 498 mg of Vitamin C. If the initial table contained 625 mg, what is the %vitamin C composition of the tablet? Answer = Blank 1. Fill in the blank, read surrounding text. %. the answer must be recorded to the correct number of sig figs and rounded correctly to receive credit.

Answer 1

To calculate the percentage of vitamin C composition in the tablet, subtract the initial mass of the tablet from the mass of the tablet with the vitamin C content, then divide the mass of vitamin C by the mass of the tablet and multiply by 100.

To calculate the percentage of vitamin C composition in the tablet, we need to compare the mass of vitamin C in the tablet to the mass of the whole tablet.

First, we calculate the mass of vitamin C in the tablet by subtracting the initial mass of the tablet from the mass of the tablet with the vitamin C content: 625 mg - 498 mg = 127 mg.

Then, we can calculate the percentage of vitamin C composition by dividing the mass of vitamin C by the mass of the tablet and multiplying by 100: (127 mg / 625 mg) * 100 = 20.32%.
