Answer:
14.02 x 10²⁴ molecules
Step-by-step explanation:
To solve this problem we will use Avogadro's number: It relates to the number of molecules (or atoms) contained in 1 mol of any given substance:
- 14.02 x 10²⁴ molecules ÷ 6.023 x 10²³ molecules/mol = 23.28 moles
Thus, 23.28 moles of water contain 14.02 x 10²⁴ molecules.
