In the question, we need to find the percent of the rda for the vitamin c in the tablet.
00:06
So for the given values, we have the molar mass of your ascarbic acid that is 1076 .12 grams.
00:16
We have also the molarity of your potassium or your kio3 rather, that is 0 .030m.
00:27
And also we have our volume that is in milliliters, which is 32 .89 milliliters based on the question that we have and the thing that we need to look for is the percent of the rda.
00:47
Now, next step, we need to find the number of moles of your kio3 reacted.
00:55
So to be able to get the most of your k -i -o -3, we need to multiply the moles of your k -i -o -3, which is 0 .0 -3, by the volume that is 32 .89, divided by 1 ,000, because we need to convert your milliters to liters.
01:18
So by multiplying your 0 .0230 by 3 .89, we have 0 .75647.
01:29
Divided by 1 ,000, we have 0 .000756 for most of your k -i -03.
01:40
Now given in the equation, we have the given equation that is, we need to write it first, equation.
01:48
We have k -i -o -3 plus 5 -k -i, hydrogen ions sealed to iodide, and also water.
02:03
We already know that the most of your k -i -o -3 is 0 .007 -564.
02:12
Now, from the other reaction for your iodine or your i2, your i2, your i2 will be react with your acorbic acid, or with the ascorbic acid.
02:26
So therefore we have i2 plus your acorbic acid.
02:34
Ascorbic acid yields to 2i minus plus dehydroacorbic acid.
02:51
Ascorbic acid.
02:55
0 .007564 of i2 required 0 .007564 moles of your acorbic acid...
