# What is the percent composition of chromium in BaCrO4?

20.5% Cr.

##BaCrO_4## is 20.5% ##Cr##

I found this answer by adding up the mass of one mole of ##Cr## and placing that number in the numerator. Then, total up the mass of ##BaCrO_4## and place that mass in the denominator. Solve and then you have your answer.
