Question

Zircon, a mineral from which cubic zirconia is made: 34.91% O, 15.32% Si, 49.77% Zr

This is what I got so far:

"O" -> 34.91(1/ 15.999)= 2.4945530908 -> 2.4945530908 / 5454869147 = 4.00116808

"Si" -> 15.32(1/28.085)= .5454869147 -> 5454869147 /5454869147 =1

"Zr" -> 49.77(1/91.224)= .545801105 ->.545801105 / 5454869147 = 0.9994705022

So once this is done, HOW do i know what number to use in order to make these three number complete in order to find out what is the empirical formula???

somone please explain!! thank you!

Explanation / Answer

Your calculations are correct

Now you got O = 4.00116808 = 4

Si = 1

Zr = 0.9994705022 = 1 (apprx)

Simple Ratio of Zr : Si : O = 1:1:4

so Empirical formula is Zr Si O4
