Can someone show me how to do this step-by-step? THANK YOU!

To answer this you need the Ksp for Ag2CrO4. My textbook says it's 1.1 x 10^-12. When Ksp is stirred into water a very small amount dissolves forming x M CrO4 2- and 2x M Ag+.
Ag2CrO4 <==> 2Ag+ + CrO4 2-
Ksp = [Ag+]2 [CrO4 2-] = (2x)^2 (x) = 4x^3 = 1.1 x 10^-12
x^3 = 2.8 x 10^-13
x = 6.5 x 10^-5 M = [CrO4 2-] = [Ag2CrO4] since 1 mole of Ag2CrO4 contains 1 mole of CrO4 2-.
