How many phosphorus atoms are contained in 158 kg of phosphorus? A)3.07 × 10²⁷ phosphorus atoms B)2.95 × 10²⁷ phosphorus atoms C)3.25 × 10²⁸ phosphorus atoms D)1.18× 10²⁴ phosphorus atoms E)8.47 × 10²⁴phosphorus atoms

Question

Quizplus · Accepted Answer

To find the number of phosphorus atoms, convert 158 kg to grams (158,000 g), then divide by the molar mass of phosphorus (approximately 30.97 g/mol) to find moles. Multiply by Avogadro's number (6.022 × 10^23 atoms/mol) to find the number of atoms, which is approximately 3.07 × 10^27 atoms.
