Answer 2

Answer:

Explanation:

1mole contains 6.023×10²³ molecules

a) 2.5 mole of Cl₂

then O₂ = 2.5 mole  because molecules are same

Mass of O₂ =2.5 moles × 32gm/mole

Mass of O₂ =80gms

b) 6.4g of Sulphur dioxide

No of moles of SO₂=6.4g/(64gm/mole)

No of moles of SO₂=0.1

then O₂ = 0.1 mole  because molecules are same

Mass of O₂ = 0.1 moles × 32gm/mole

Mass of O₂= 3.2 gm

c) 1mole contains 6.023×10²³ molecules

no of moles=  6.023×10²²/ 6.023×10²³= 0.1 mole

then O₂ = 0.1mole  because molecules are same

Mass of O₂= 0.11moles × 32gm/mole

Mass of O₂= 3.2 gm
