How many 02 atoms are in 2.50 moles of SO2?
回答 (1)
SO₂ contains O atoms. SO₂ contains NEITHER O₂ molecules NOR O₂ atoms.
No. of moles of SO₂ molecules = 2.50 mol
Each mole of SO₂ molecules contains 2 moles of O atoms.
No. of moles of O atoms = 2.50 × 2 = 5.00 mol
Each mole of O atoms is equivalent to 6.02 × 10²³ atoms.
No. of O atoms = 5.00 × (6.02 × 10²³) = 3.01 × 10²² ...... (Ans)
