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