the process to determine which of the following compounds has the most silver in one mole : AgCl 2 AgNO 3 , Ag 2 O, Agl

The compound silver oxide, Ag₂O has the most silver in one mole of the compound.

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.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

we need the questions , i may then you.
