Finding the emperfind me empirical and chemical formula for 7.19% phosphorus and 92.81% bromine

To find the empircal formula start by looking at the masses of each element.

1) 7.19G* 1 mol/ 30.97 = 2.32mol Phosphorus

92.81G * 1 mol/ 79.90 = 1.16 Bromine

2) Since none of them give exact whole numbers you need to didvide each by the smallest amount

2.32/1.16 = 2 mol Phosphorus

1.16/1.16= 1 mol Bromine

3) write your answer

BrP2

* the 2 shoud be denoted as a subscript

and I believe that this same answer is this. compunds chemicial formula

c. 75.7

i think that is the right
