What is the formula of natural chromite?
feCr2O4
What is the percent of oxygen by mass in a pure sample of FeCr2O4?
To determine the percentage of oxygen in FeCr2O4, you would first calculate the molar mass of the compound (iron(II) chromite) using the atomic masses of each element (Fe = 55.85 g/mol, Cr = 51.996 g/mol, O = 16 g/mol). Then, calculate the molar mass percentages of each element within the compound, and finally, determine the percentage of oxygen by mass in the compound.
What are some compounds chromium is found in?
Chromium chlorides, Chromite (FeCr2O4), and Chromium oxide (Cr2O3).
What is the standard state of chromium?
The natural state of the element chromium is a solid metal. The natural state just indicates what the element is.
What is the empirical formula of a mineral having the percent composition 28.59 O 24.95 Fe 46.46 Cr.?
O: 28.59 g x 1 mole O/16 g = 1.79 moles OFe: 24.95 g x 1 mole/55.8 g = 0.447 moles FeCr: 46.46 g x 1 mole/52 g = 0.893 moles CrDividing through by 0.447 one gets 4O, 1Fe and 2CrEmpirical formula = FeCr2O4
