Edward Potter · Answer 1

We can say that for every 2 atoms of F, there is a mass of 0.2894 g as evident from the compound XeF2. Now to find for f, we can say that there are n atoms of F for every 0.8682 g of F. Taking the proportion:

2 atoms / 0.2894 g = n / 0.8682 g

Calculating for n:

n = 2 * 0.8682 / 0.2894

n = 6
