So for this problem, we want to calculate the mass of iodine that will react with 20 .4 grams of aluminum, and our final compound is going to be ali3.
00:14
So we know that our starting quantity is 20 .4 grams of aluminum.
00:24
And we know that per every one wall of aluminum, that its atomic mass is 26 .98 grams, or amu.
00:36
And now i want to find the multiple ratio of aluminum and iodine.
00:41
Well, if you look at this compound, we said there's three iodine atoms per every mole per every aluminum atoms.
00:48
So the multiple ratio is just going to be three moles of iodine to then one mole of aluminum.
00:56
But there's a problem here.
00:59
The problem is that a singularly atomic eye is not the natural form of iodine in nature...
