The total number of atoms in 0.111 mol of Fe(CO)₃(PH₃)₂ is ________. A)15.0 B)1.00 × 10²⁴ C)4.46 × 10²¹ D)1.67 E)2.76 × 10^-²⁴

Question

Quizplus · Accepted Answer

The compound Fe(CO)₃(PH₃)₂ contains 1 Fe, 3 C, 3 O, 2 P, and 6 H atoms, totaling 15 atoms per molecule. The number of molecules in 0.111 mol is 0.111 × Avogadro's number (6.022 × 10²³), which gives approximately 6.68 × 10²² molecules. Multiplying this by 15 atoms per molecule gives approximately 1.00 × 10²⁴ atoms.
