ion is phosphate.
Name of
ion is ammonia.
Name of
ion is acetate.
Name of
ion is oxalate.
Thus, we can conclude that the symbols and names for the ions given correctly is OH-:hydroxide
Molar mass Cu(OH)2 => 97.561 g/mol
Therefore:
1 mole Cu(OH)2 ------------ 97.561 g
? moles Cu(OH)2 ----------- 68 g
= 68 x 1 / 97.561
= 68 / 97.561
= 0.696 moles of Cu(OH)2
