Lithium bromide (LiBr) is a compound, not a cation. The cation is Li+.
(7.6g LiBr)/(86.84g/mol) x (1molLi/1molBr) = .0875 mol Li or with sig figs, .088
The symbol for a bromide ion is Br-.
The cation is Mn(3+).
The chemical formula (not symbol) of potassium bicarbonate is KHCO3.

Cu
A monovalent cation; the symbol is I (Roman).
The symbol of the cation of FeCl2 is Fe2+. A cation is a positively charged ion and to find the formula of any compound you must balance the cations with the anions.
symbol of cation = K+ symbol of anion = CL-
The symbol for the cation formed when a potassium atom loses one electron is K+, and is named the potassium ion.
