Answer:

The percentage of potassium in the given complex is 35.54 %.

Step-by-step explanation:

Mass of potassium in
K_3Fe(CN)_6 = 3 × 39.10 g mol=117.3 g/mol

Molar mass of
K_3Fe(CN)_6 =329.15 g/mol

Percentage of potassium (K) in the the complex:


\% K=\frac{\text{mass of potassium}}{\text{molar mass of complex}}* 100


\%K=(117.3 g/mol)/(329.15 g/mol)* 100=35.54\%

The percentage of potassium in the given complex is 35.54 %.
