Calculate the molar solubility of Cu(OH)2, Ksp = 2.2 × 10–20, in 0.32 M NH3, in mol/L. Don't forget to use the complexation reaction Cu2+ + 4 NH3 ? Cu(NH3)42+, K = 5.0 × 1013.

I thought I just had to find x, the extra information is throwing me off.

B(t) = 50 *e0.5tAnswer Question

by taylor-a... Member since:April 27, 2009Total points:969 (Level 2)If you have a graphing calculator, plug the equation into the y=.
Expand your window so that you can see the population (probably the y axis) untill you can see 1000. Some cushion would be helpful so make the window a little bigger.
Plug 1000 into the y= also and find where the line intersects your function.
(If you didn't know, the e is above the divide symbol on the calculator.)
I hope this helps.
