Question

how to solve this plz give me answer step by step ☺️

Answer 1

It would be approx 1.0 * 10^-22

Answer 2

→ We know that 1 mole of SO₂ weighs 64 grams

→ Also, 1 mole of SO₂ contains Avogadro number of SO₂ molecules.

→ Hence Avogadro number of SO₂ molecules weigh 64 grams

→ that is, 6.022 x 10²³ SO₂ molecules weigh 64 grams

So, the mass of 1 molecule of SO₂ = 64/6.022 x 10²³ = 1.06 x 10⁻²² grams

Hope it helps!!
