Answer:

b) 3.000 mol S

Explanation:

using Avogadro's constant

1 mol = 6.02 × 10^23 atoms

we need to find the number of moles for 1.806 × 10^24

x = 1.806 × 10^24

putting it together we now have:

1 mol = 6.02 × 10^23 atoms

x = 1.806 × 10^24

cross multiply

6.02 × 10^23 x = 1.806 × 10^24

divide both sides by 6.02 × 10^23

x = (1.806 × 10^24) ÷ (6.02 × 10^23) = 3 mol
