The volume occupies by one molecules of water is [density of water =1g/cm³
Options
(a) 22400 cm³
(b) 6.02 ˣ 10⁻²³cm³
(c) 3.0 ˣ 10⁻²³cm³
(d) 11200cm³
Correct Answer:
3.0 ˣ 10⁻²³cm³
Explanation:
Given density of water = 1 g/cm³, Therefore 1 g of H₂O₂ = 1 cm³ of H₂O, 1 mole of water = 18 g of H₂O = 18 cm³ of H₂O, Therefore , 6.022 ˣ 10²³ molecule of water occupy volume = 18 ml, Therefore 1 molecule of water occupy volume = 18 / 6.022 ˣ 10²³ = 2.99 ˣ 10⁻²³.
