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%
K, potassium, is a group 1 element so it always has a +1 charge. O, oxygen, almost always has a charge of -2, and does so in this case.
7(-2) + 2(+1) + 2(Cr) = 0
-14 + 2 + 2(Cr) = 0
-12 + 2(Cr) = 0
2(Cr) = 12
Cr = 6
Each Cr (chromium) has a charge of +6
The percentage of chromium depend on the specific type of th alloy; name the desired alloy for an answer !
Chromium is just that - chromium. It is a metallic element.
chrome is useally found in chromite, thats why its called chromite like chrome aha
Potassium dichromate (K2Cr2O7) contain 35,361 % chromium.

Chromium fluorides are: Chromium difluoride: CrF2 Chromium trifluoride: CrF3 Chromium tetrafluoride: CrF4 Chromium pentafluoride: CrF5 Chromium hexafluoride: CrF6
Ruby is aluminium oxide; chromium is only a natural dopant, in traces. The concentration of chromium is not constant in rubies.
Chromium: 16-18,5 % Nickel: 10-14 % For details see the link below.
Ruby is aluminium oxide (Al2O3) with chromium as an impurity.
