Answer:
0,61 moles of potassium permanganate equal 3.67 x 10^23
Explanation:
The mole is defined as the amount of compound that contains Avogadro's number of particles (atoms, molecules, ions, electrons, etc.). Avogadro's number has a value of: 6,023 · 10e23 particles.
6,023 · 10e23 particles.---1 mol KMn04
3.67 x 10e23 particles-----x=
x= ( 3.67 x 10xe23 particles1 mol KMn04 )/6,023 · 10e23 particles=0,609 moles
In the <em>trial structure</em> (1st image below), every atom has an octet.
Valence electrons = 20
Valence electrons available = 4 + 2 +10 = 16
The trial structure has 4 electrons too many. The actual structure must have <em>two double bonds or one triple bond.</em>
The second image shows two possible Lewis structures.
