Explanation:
Detailed explanation-1: -9g=6.0222×1023 molecules of H2O=3.011×1023 molecules of H2O.
Detailed explanation-2: -One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).
Detailed explanation-3: -Step 1: Identify the element and the amount of the element that we have in the problem. Step 2: Find the mass of 1 mole of the element. Step 4: Find how many atoms are in the number of moles we found in Step 3 by multiplying the number of moles by Avogadro’s number.
Detailed explanation-4: -Therefore, the number of moles in 9 gm of H₂O is 0.5.
