Best Answer

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
