Atoms In 5.80 Moles Of He

Jun 25, 2008  · Trending Now. Answers. Best Answer: To convert from moles to atoms, the conversion factor to use is Avogadro’s number, which is 6.022*10^23 atoms per one mole, so to cancel out moles, leaving only atoms: 5.80 mol He * 6.022*10^23 atoms He/ 1 mol He. This cancels out moles, leaving 3.49*10^24 atoms He.
