Answer:
7.8286×10^21 particles
Explanation:
atomic mass of potassium = 39.1 u
1 u = 1 g/mol
Potassium (K) = 39.1 g/mol × 2 = 78.2 g/mol
Oxygen (O) = 16 g/mol × 1 = 16 g/mol
K₂O = 94.2 g/mol
1.224 g / 94.2 g/mol = .013 moles
Avogadro's number = 6.022×10²³
particles = moles x Avogadro's number
particles = .013 moles x 6.022×10^23
particles = 7.8286×10^21 particles
