Answer:
there are 3.63*10⁻² moles of ammonium anions
Explanation:
since the ammonium carbonate is
(NH₄)₂(CO₂)
and the ammonium carbonate dissociate according to
(NH₄)₂(CO₂) →2*NH₄⁺ + CO₂²⁻ ( we will neglect other carbonate species for simplicity)
then each mole of ammonium carbonate generates 2 moles of ammonium anions , then
n AC = 2* n A
where n represents moles AC represents ammonium carbonate and A represents ammonium anions
also we know that
n AC = m AC / M AC
where
m = mass of ammonium carbonate = 6.595 g
M = molecular weight of ammonium carbonate = 96.09 g/mol
then
n AC = m AC / M AC = 6.595 g/ 96.09 g/mol = 7.25*10⁻² moles of ammonium carbonate
thus
n AC = 2* n A → n A = n AC /2 = 7.25*10⁻² /2 = 3.63*10⁻² moles of ammonium anions
