Answer: The empirical formula is .
Explanation:
So, the mass of each element is given:
Mass of Se = 1.443 g
Mass of O = 0.5848 g
Step 1 : convert given masses into moles.
Moles of Se=
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For Se =
For O =
The ratio of Se: O = 1: 2
Hence the empirical formula is .
