To determine the total number of atoms in 0.250 moles of carbon dioxide (CO2), we need to use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole.
One molecule of carbon dioxide contains one carbon atom and two oxygen atoms. Therefore, the number of atoms in 0.250 moles of CO2 can be calculated as follows:
Number of molecules = moles x Avogadro's number
Number of molecules = 0.250 mol x 6.022 x 10^23 molecules/mol
Number of molecules = 1.5055 x 10^23 molecules
Total number of atoms = Number of molecules x Number of atoms per molecule
Total number of atoms = 1.5055 x 10^23 molecules x (1 carbon atom + 2 oxygen atoms)
Total number of atoms = 1.5055 x 10^23 x 3
Total number of atoms = 4.5165 x 10^23 atoms
Therefore, there are approximately 4.5165 x 10^23 atoms in 0.250 moles of carbon dioxide.
