Question
Calculate the number of hydrogen atoms in 1.00 mol of water (H₂O).
Correct Answer
Option B is the correct answer.
Detailed Explanation
1 mol H₂O contains 2 mol H atoms. Number of H atoms = 2 × 6.022 × 10²³ = 1.2044 × 10²⁴.
Hint
Multiply the number of moles of the compound by the number of atoms of that element per formula unit, then by Avogadro's number.
