To determine the number of fluorine atoms in a sample containing 3.3 moles of BeF2, we need to follow these steps:<br /><br />1. Determine the number of moles of fluorine atoms in the sample.<br />2. Convert the number of moles of fluorine atoms to the number of fluorine atoms.<br /><br />Step 1: Determine the number of moles of fluorine atoms in the sample.<br />Since each molecule of BeF2 contains 2 fluorine atoms, the number of moles of fluorine atoms in the sample is:<br />Number of moles of fluorine atoms = 3.3 moles of BeF2 × 2 = 6.6 moles of fluorine atoms<br /><br />Step 2: Convert the number of moles of fluorine atoms to the number of fluorine atoms.<br />To convert the number of moles of fluorine atoms to the number of fluorine atoms, we need to use Avogadro's number, which is 6.022 × 10^23 atoms per mole.<br />Number of fluorine atoms = 6.6 moles of fluorine atoms × (6.022 × 10^23 atoms/mole) = 3.97 × 10^24 fluorine atoms<br /><br />Therefore, the correct answer is:<br />$3.97\times 10^{24}$ Liatoms
