Homework Statement
Cu2+OH-, and Br- form a mixed salt formula Cux(OH)yBrz. In an experiment to determine the values of x, y, and z in the formula of this compound, .760 g CuBr2 (223.4 g/mol) was dissolved in water and reacted with 10.22 ml 0.555M NaOH. Assume that in this reaction, all of the Cu2+ from the CuBr2 and all of the OH- from the NaOH were incorporated into the product but that not all of the Br- was used.
Calculate the number of moles of Cu2+ and OH- in the product.
Homework Equations
The Attempt at a Solution
10.22mL * 1/1000L * .555M NaOH = .00567 mols OH-
I think that is right...but it's finding the moles of Cu that is stumping me.
.760g CuBr2 * 2H2O * 1/259.4 = .00293 mol CuBr2
Now I don't know how to get from that to mols of just Cu. I don't have a volume or anything.
