Answer:
The compound silver oxide, Ag₂O has the most silver in one mole of the compound.
Step-by-step explanation:
From the formula of each of the compounds given:
AgCl₂ : there are one mole of silver atoms for every two moles of chlorine atoms in the compound, silver chloride, AgCl₂
AgNO₃: there are one mole of silver atoms for every one atom of nitrogen and three atoms of oxygen in the compound, silver trioxonitrate (v), AgNo₃.
Ag₂O : there are two atoms of silver for every atom of oxygen in one mole of silver oxide.
AgO : there are one mole of silver atoms for very one mole of iodine atoms in one mole of silver iodide.
Therefore, one mole of silver oxide, Ag₂O has the most silver in one mole of the compound.
