Determine the molar solubility of copper(II) cromate in a 0.75 M copper(II) chloride solution.(The Ksp of copper(II) cromate is 2.87*10^-8). I have no idea how to solve this problem!!!
A fossil was analyzed and determined to have a carbon-14 level that is 60.0 that of living organisms. How old is the fossil?
C-14 has a half life is 5730.
Can someone show how to set this up to get t(time)???
