Na2CO3
2 * 2 = 4 moles sodium.
===========================
It does NOT form molecules. When AlCl3 'breakdown ' it form the IONS Al^(3+) & 3 Cl^(-) AlCl3(s) IS a molecule.
The dissociation of ZnBr2 is: ZnBr2--------- Zn(2+) + 2 Br-
I assume that is 28.0 grams.28.0 grams MgCl2 (1 mole MgCl2/95.21 grams)= 0.294 moles magnesium chloride==========================Now,One mole Mg 2+ = 0.294 moles Mg 2+ ions=============================2 moles Cl - = 0.588 moles Cl - ions=========================
Sugar is a non-electrolyte. This means when dissolved in water, it will not dissociate into ions. Hence there will be only ONE particle when sugar is added to water.
PLATO: hydrogen ions
1.5 moles

Because they dissociate into charged ions. Because they dissociate into charged ions.
hydroxide ions
10000
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
oxygen
PLATO: hydrogen ions
Dissociation of sodium carbonate produce ions Na+ and (CO3)2-.
