What is the empirical formula of Fe?
The “non-whole number” empirical formula of the compound is Fe1O1.5. Multiply each of the moles by the smallest whole number that will convert each into a whole number. Fe:O = 2 (1:1.5) = 2:3.
What is the empirical formula for iron sulfide?
Pyrrhotite, which is chemically called iron sulfide, has the ideal formula FeS (Fe = iron, S = sulfur). This formula means that in ANY AMOUNT of pyrrhotite, the ratio of iron to sulfur will be 1:1.
How do you find the empirical formula of magnesium oxide and calcium oxide empirical formula?
The empirical formula is the simplest whole-number ratio of atoms in a compound.
- The ratio of atoms is the same as the ratio of moles.
- Mass of Mg = 0.297 g.
- Mass of magnesium oxide = mass of Mg + mass of O.
- 0.493 g = 0.297 g + mass of O.
- Mass of O = (0.493 – 0.297) g = 0.196 g.
- There is 1 mol of Mg for 1 mol of O .
