There are 337.23 × 10²³ atoms in 4 moles of aluminum sulfite Al₂(SO₃)₃.
Explanation:
The questions ask how many atoms are in 4 moles of aluminum sulfite Al₂(SO₃)₃?
To answer this we use the Avogadro's number to devise the following reasoning:
if in 1 mole of Al₂(SO₃)₃ there are 14 × 6.022 × 10²³ atoms
then in 4 moles of Al₂(SO₃)₃ there are X atoms
X = (4 × 14 × 6.022 × 10²³) / 1 = 337.23 × 10²³ atoms

Explanation:
S is in 3d period, so it has 3 levels
1 level has 2 electrons, 2d level 8 electrons, 3d level 6 electrons
Answer:
1.02x10^24 atoms
Explanation:
The coefficients (the numbers before each susbtance) in this equation tell us that for every 2 moles of hydrogen used, there will be 1 mole of tin produced. This is a fixed ratio, which means if we use 4 moles of H2, 2 moles of tin will be produced.
One mole contains Avogadro's number of atoms (6.02 x 10^23). So two moles would contain twice as many atoms as this.
2 x 6.02x10^23 = 1.02x10^24 atoms.
