How many atoms are present in 3 moles of chromium?
6.02 × 10 23atoms
52.0 atoms
1.80 × 10 23atoms
1.80 × 10 24atoms
1.80 × 10^24 atoms
To determine the number of atoms in 1 mole of any element, you can use Avogadro's number, which is 6.02 × 10^23 atoms/mole. So, for 3 moles of chromium, you would have 3 x 6.02 × 10^23 = 1.80 × 10^24 atoms.
