To determine the number of fluorine atoms in a sample containing 3.3 moles of BeF2, we need to follow these steps:1. Determine the number of moles of fluorine atoms in the sample.2. Convert the number of moles of fluorine atoms to the number of fluorine atoms.Step 1: Determine the number of moles of fluorine atoms in the sample.Since each molecule of BeF2 contains 2 fluorine atoms, the number of moles of fluorine atoms in the sample is:Number of moles of fluorine atoms = 3.3 moles of BeF2 × 2 = 6.6 moles of fluorine atomsStep 2: Convert the number of moles of fluorine atoms to the number of fluorine atoms.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.Number of fluorine atoms = 6.6 moles of fluorine atoms × (6.022 × 10^23 atoms/mole) = 3.97 × 10^24 fluorine atomsTherefore, the correct answer is: Liatoms
