Let volumetric size of a water molecule = v
Since, 1 mole of water consists of molecules of water.
Thus, total volume of 1 mole of water =
Substitute the value of total volume of 1 mole of water i.e. 22.4 L in above formula.
Convert the unit litre to angstrom
=
=
Therefore, the volumetric size of the water molecule is
9moles of O₂
Explanation:
Given parameters:
Number of moles of KClO₃ = 6moles
Unknown:
Number of moles of O₂ = ?
Solution:
KClO₃ is often known to undergo a decomposition reaction to produce KCl and O₂.
2KClO₃ → 2KCl + 3O₂
From the given equation, we know;
2 moles of KClO₃ will produce 3 mole of O₂
6 mole of KClO₃ will produce = 9moles of O₂
