Ba = 137.327
Cr = 51.9961
O = 15.9994
BaCrO4 = 137.327 + 51.9961 + 4(15.9994) =
253.3207 g/mol
51.9961 / 253.3207 = 0.20526
0.20526 x 100 = 20.526
The answer is:
20.526%
The percent composition of Cr2O3 is approximately 68% Chromium (Cr) and 32% Oxygen (O).
Chromium is a chemical element that is naturally found as a solid in its metallic form. It is considered a homogeneous substance because it has the same uniform composition throughout its structure.
Red spinel gets its color from traces of chromium within its chemical composition. Chromium is responsible for the vibrant red hue seen in red spinel gemstones.
When chromium (III) nitrate is mixed with ammonia, a pale blue-green precipitate of chromium hydroxide is formed. This reaction is pH-dependent, with the specific color and composition of the precipitate varying based on the concentration of ammonia and the pH of the solution.
Nichrome is mainly composed of nickel and chromium. It typically contains around 80% nickel and 20% chromium, although there can be variations in the exact proportions depending on the specific grade or use of the alloy.
The percent composition of Cr2O3 is approximately 68% Chromium (Cr) and 32% Oxygen (O).
Ruby is aluminium oxide (Al2O3) with chromium as an impurity.

HSS is 18% Tungsten, 4% Chromium, 1% Vanadium, 0.7% Carbon and rest Iron
Chromium is a pure substance. It is a naturally occurring element with a specific atomic structure and chemical composition. It is not composed of different types of atoms or molecules, which is a characteristic of pure substances.
The stable isotope of chromium is chromium-52. Other isotopes of chromium include chromium-50, chromium-53, chromium-54, and chromium-55, but not chromium-151.
