A sample of K₃Fe(CN)₆ contains 1.084 × 10²⁴ carbon atoms. How many potassium atoms are in the sample?

Question

Quizplus · Accepted Answer

In K₃Fe(CN)₆, there are 6 carbon atoms per formula unit. Therefore, the number of formula units is 1.084 × 10²⁴ carbon atoms / 6 = 1.807 × 10²³ formula units. Since there are 3 potassium atoms per formula unit, the number of potassium atoms is 3 × 1.807 × 10²³ = 5.420 × 10²³ atoms.
