To find the number of lithium atoms in a sample containing 2.4 moles of
, we need to follow these steps:1. Determine the number of moles of lithium atoms in the sample. Since each molecule of
contains 2 lithium atoms, we multiply the moles of
by 2 to get the moles of lithium atoms.2. Use Avogadro's number (
atoms/mole) to convert the moles of lithium atoms to the number of lithium atoms.Let's calculate:1. Moles of lithium atoms = 2.4 moles of
× 2 = 4.8 moles of lithium atoms2. Number of lithium atoms = 4.8 moles ×
atoms/mole =
lithium atoms
