Please help. I’m super confused. Thanks. ^_^

Ksp = [A++]*[B-]^2
?M AB2 = 3.90 g/L x 1 mole / 293 g = 0.0133 M
[A++] = 0.0133 M
[ B-] = 0.0266 M
Ksp = [0.0133]*[ 0.0266 ]^2 = 9.41x10E-6

AB2=3.90g/L x 1 mole/ 293 g=0.0133 M
[A++]= 0.0133 M
[B-]= 0.0133 x 2 = 0.0266
Ksp= [0.0133] x [0.0266]^2 = 9.41 x 10^-6

multiply by two, since the equation is AB2 –> A^2+ + 2B^2-
Therefore, 2*.0133=.0266
However, since the solubility equation requires the coefficient to be moved up as a power, you still have to square the .0266

how’d you get the B-
