Answer:
They display the number of valence electrons surrounding an element or compound.
Explanation:
Number of particles inside a sugar bowl = 4.4 x 10²³
<h3>Further explanation</h3>
Given
The molar mass of sugar = 342.3 g/mol
mass of sugar = 250 g
Required
Number of particles
Solution
1 mol = 6.02 x 10²³ particles
mol of sugar :

mol = 250 g : 342.3 g/mol = 0.73 mol
Number of particles :
N = n x No
N = 0.73 x 6.02 x 10²³
N = 4.39 x 10²³ ≈ 4.4 x 10²³
I’m soooo confusing with what your question is lol
