Answer:

O5F2.

Explanation:

Element Flourine and oxygen

percentage by mass F=32.1%,O=67.9%

Relative no. of moles of F, 32.1÷19=1.64.and O ,67.9÷10=4.29.

Simple ratio of moles F,1.64%1.64=1 and O ,4.24÷1.64=2.50

Some whole ratio F=1×2=2

O=2.5 ×2=5.

Simples whole number ratio is 2:5 .

Hence the empirical formula of compound is O5F2.
