Answer:
0.012 mol
Explanation:
Step 1: Given data
Atoms of sulfur: 7.0 × 10²¹ atoms
Step 2: Calculate the moles corresponding to 7.0 × 10²¹ atoms of sulfur
In order to convert atoms to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ atoms of sulfur in 1 mole of atoms of sulfur.
7.0 × 10²¹ atoms S × 1 mol S/6.02 × 10²³ atoms S = 0.012 mol S
