determine the molarity of each of the ions present in the following aqueous salt solutions (assume 100% ionization)

1.25 M CuBr2

how many grams of each ion would be present in 100mL of each solutions.

1 answer

M CuBr2 = 1.25.
There is 1 Cu atom in 1 molecule CuBr2; therefore, M Cu^2+ ion is 1.25.
There are 2 Br atoms in 1 molecule CuBr2; therefore, M Br^- = 2*1.25 = ?

mols ion = M x L = ?
Convert to g; g = mols x ionic mass
