<span>number of moles= mass / molecular mass
mass=131.50g
molecular mass of Zn(NO3)2 =189.39 g/mol
number of moles = 131.50 g/189.39 g/mol =0.69433 mol</span>
The answer is Molecule. After a pair of shared electrons orbit around the nuclei of both atoms
Lithium Bromine (LiBr) is formed from them....
<span>Solutes become electrolytes by ionizing. Ionic compounds therefore make good electrolytes; covalent compounds don't.</span>
