Answer:
See the image below
Explanation:
To draw a Lewis structure of a molecule, you place the least electronegative atom (Xe) as the central atom, with the more electronegative atoms (O) surrounding it.
Then you distribute the electrons around the atoms, giving every one an octet and placing any extra electrons on the central atom.
This procedure gives you four possible Lewis structures, so the actual structure is a resonance hybrid of them all.
Structure D has no formal charges, so it is the major contributor.
Hey there!:
<span>Use the Avogadro constant :

1 mole -------------- 6.02*10²³ molecules
0.0524 moles -------- molecules H2O
molecules H2O = 0.0524* ( 6.02*10²³) / 1
molecules H2O = 3.15*10²² / 1
= 3.15*10²² molecules H2O
