The image attached below is the correct representation of a face-centered cubic unit cell model. To create this model, you have to place 6 balls in the centers of each of the cube's faces and 1 ball for every corner of the cube which sums up to 8 balls. Therefore, the answer is: <span>
<em>eight balls at the corners of a cube, and six balls in the centers of the cube's faces.</em></span>
Iodine value is a measure of the degree of unsaturation in fats and oils. It is essentially the number of grams of iodine consumed by 100 g of fat. If the iodine number is in the range of 0-70 then it is a fat, any value above 70 is considered an oil.
Formula:
Iodine number = (ml of 0.1 N Thiosulphate blank- ml of 0.1N thiosulphate test) * 12.7 *100/1000* wt of sample
vol of thiosulphate required to titrate test sample (given oil) = 1 ml
wt of sample = 0.2 g
Information on the volume of thiosulphate required to titrate the blank solution is essential for calculation.
Iodine number = (X-1.0) * 12.7 * 100/1000* 0.2 = (X-1.0)*6.35
