10.0 ml of a 0.1 M solution of a metal ion solution of a Metal ion M2+ is mixed with a 10.0 ml Solution of a 0.1 M substance L. The following equation is established: M2+(aq)+2L(aq)<>ML2 2+(aq). At equilibrium the concentration of L is 0.01M. What is the equilibrium concentration of [ML2]2+? Please help me understand what I am doing wrong.

Best ResponseYou've already chosen the best response.6i know how to solve 10.0 mL of a 0.100 M it's comes out like this, Hope fully this can give you a little start : Change everything to moles. Multiply Molarity by Volume to get moles. First change L in moles. You can figure out how many moles of each are in equilibrium. If L = x moles, M2+ = x moles, ML2 = 3x moles. PS. To find L moles multiply the final concentration (given above) by the total volume, 200mL. Divide the moles by the total volume to get the concentration.

Best ResponseYou've already chosen the best response.0Thanks for trying Hershey. The important point that I got from you is that I have to redo the calculations with the new volumes.

Best ResponseYou've already chosen the best response.0If I did it correctly, the answer should've been [M2+] = 0.04 M.
