Question

how many protons are their in 20 moles SO2

Answer 1

64. 0638 is the number of protons are there in 20 moles of SO2. I hope this will help you.

Answer 2

1 molecule of SO₂ has 16 + 8 + 8 = 32 protons

1 mole of SO₂ contains Avogadro number of molecules.

so, 1 mole of SO₂ contains 32 x (6 x 10²³) number of protons

20 moles of SO₂ contain 20 x 32 x 6 x 10²³ protons

                                  → 3.84 x 10²⁶ protons
