To solve this problem, we need to find the number of lithium atoms in the sample containing 24 moles of H2O.Given information:- The sample contains 24 moles of H2O.Step 1: Calculate the number of lithium atoms in the sample.- The molecular formula of water is H2O, which means each molecule of water contains 2 hydrogen atoms and 1 oxygen atom.- The atomic number of lithium is 3, which means each lithium atom has 3 protons.Number of lithium atoms = (Number of moles of H2O) × (2 × Avogadro's number)Number of lithium atoms = 24 moles × (2 × 6.022 × 10^23 atoms/mol)Number of lithium atoms = 4.30 × 10^23 lithium atomsTherefore, the correct answer is:
