Question

Find the amount of water containing 14.02 * 10²⁴ molecules​

Answer 1

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.
