How many molecules of SO₃ can be formed from 0.75 moles of O₂ (assuming excess SO₂) from the following UNBALANCED equation?
SO₂(g) + O₂(g) → SO₃(g)

Respuesta :

2 SO₂(g) + O₂(g) => 2SO₃(g)

moles SO₃ = 2/1 x moles O₂ = 2/1 x 0.75 = 1.5 moles

molecules = 1.5 x 6.02 x 10²³ (avogadro's number) = 9.03 x 10²³ molecules
