How many sodium atoms are present in 2.00 mol of sodium metal?
A.1.20 × 10²⁴ atoms
B.6.02 × 10²³ atoms
C.3.01 × 10²³ atoms
D.2.00 × 10²³ atoms
Explanation
Core Concept
Multiply moles by Avogadro's number: 2.00 mol × 6.022 × 10²³ atoms/mol = 1.20 × 10²⁴ atoms. Avogadro's number is the bridge between the mole and particle counts.
Correct Answer
A1.20 × 10²⁴ atoms
