Final answer:
A sample of 0.585 moles of krypton (Kr) contains 3.523\u00d71023 krypton atoms, calculated by multiplying the number of moles by Avogadro's number (6.022\u00d71023 atoms/mole).
Step-by-step explanation:
To determine how many atoms are in a sample of 0.585 moles of krypton (Kr), we use Avogadro's number, which is 6.022\u00d71023 atoms per mole. This is because one mole of any substance contains Avogadro's number of atoms or molecules.
The calculation for the number of atoms in 0.585 moles of Kr would be:
Number of atoms = (Number of moles) \u00d7 (Avogadro's number)
Number of atoms = (0.585 moles) \u00d7 (6.022\u00d71023 atoms/mole)
Number of atoms = 3.523 \u00d71023 atoms
Therefore, a sample of 0.585 moles of krypton contains 3.523 \u00d71023 krypton atoms.
