Question

What is the number of atoms in 3.54 mol S

Answer 1

Answer : 2.13 ×10^24 atoms

explanation :

- One mole of (S) contains Avogadro’s number of atoms (6.02×10^23 molecules),

- Using cross multiplication,

1 mol of (S) → 6.02 ×10^23 atoms

3.54 mol of (S) → ?

Hence, the number of atoms in 3.54 mol S = 3.54 × 6.02 ×10^23 / 1 = 21.31 ×10^23 = 2.13 ×10^24 atoms ..
