What is the maximum amount of #IF_7# that can be obtained from 25.0 g fluorine in the equation #I_2 + F_2 -> IF_7#?
You need a stoichiometric equation. You can make a mass of approx.
I introduced the half-coefficient because it makes the arithmetic a little bit easier. I am certainly free to do so. The stoichiometry dictates that 1 equiv of diiodine reacts with 7 squiv difluorine.
Given stoichiometric iodine, we can form
And thus a mass of
It would not be my choice to do this reaction. I am too fond of my 10 fingers, and 2 eyes.
