Answer: AgF
Explanation: 85 / 108 (the relative atomic mass of Ag) = 0.79
15 / 19 (the RAM of F) = 0.79
This is a 1:1 ratio so the empirical formula is AgF.
AgF is the empirical formula of a compound that contains 85% Ag and 15% F by mass.
A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Molar mass of Ag =108 amu
[tex]Moles = \frac{mass}{molar \;mass}[/tex]
85 ÷ 108 = 0.79
The molar mass of F = 19amu
[tex]Moles = \frac{mass}{molar \;mass}[/tex]
15 ÷ 19 = 0.79
This is a 1:1 ratio so the empirical formula is AgF.
Hence, AgF is the empirical formula of a compound that contains 85% Ag and 15% F by mass.
