Question

Which represents the empirical formula for X4Y8?

A. XY2
B. X2Y4
C. X4Y8
D. XY

Answer 1

The correct answer is A. XY2

Step-by-step explanation:

I just took the test.

Answer 2

Answer: The Correct option is A.

Explanation: Empirical formula of a molecule is defined as the simplest whole number ratio of atoms present in that molecule.

So, for a molecule having formula
`X_4Y_8`, the simplest whole number ratio becomes when we divide the stoichiometry by 4, which makes up the formula as
`XY_2`.

Therefore, the correct option is A.
