If one wants 100g of Ag, how much ag2o is needed?
1 answer:
Mass Ag₂O needed = 107.416 g
<h3>Further explanation</h3>Given
100 g Ag
Required
mass of Ag2O
Solution
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
mass of Ag in Ag2O :
= ((2 x Ar Ag)/molar mass Ag2O )x mass Ag2O
Ar Ag : 107,8682 g/mol
MW Ag₂O = 231,735 g/mol
Input the value :
mass Ag₂O=(mass Ag x MW Ag₂O) : (2 x Ar Ag)
mass Ag₂O = (100 g x 231,735 g/mol) : ( 2 x 107,8682 g/mol)
mass Ag₂O = 107.416 g

C₈H₁₈ is a non-electrolyte
Why?
Electrolytes are substances that dissociate into ions when dissolved in water. In order to do that, they need to have bonds that are polar enough to be able to dissociate, and the ions formed need to be soluble in water.
C₈H₁₈ is a compound that has a low electronegativity difference between its atoms, making it to be a covalent compound where electrons are shared, and making it non-polar, and difficult to dissociate. Thus, it is a non-electrolyte.
One possible structure for C₈H₁₈ is attached below. It's called octane.
Have a nice day!
