The answer is: the percent composition of chromium is 20.52%.

Ar (Cr) = 52; atomic mass of chromium.

Mr (BaCrO₄) = 253.3; molecular mass of barium chromate.

ω (Cr) = Ar (Cr) : Mr (BaCrO₄) · 100%.

ω (Cr) = 52 : 253.3 ·100%.

ω (Cr) = 20.52%; the percent composition of chromium in barium chromate.
