Answer:
2.08×10^24 atoms
Explanation:
set up a mole to atom ratio:
3.47moles 1 mole
------------------ = ----------------------------
x atoms 6.02×10^23 atoms
cross multiply:
3.47 mole × 6.02 × 10^23 = 2.08×10^24 atoms
Therefore the largest atoms are on the left and the smallest on the right. So sodium (Na) has the largest atomic radius, as the valence electrons are the least attracted to the nucleus
