what mass of Silver oxide would be required to produce 100.0 g. of silver.

Answer 1

Ag2O ==> 2Ag + ?
The equation isn't balanced but it lets you know that you can produce 2 mols Ag for each mols Ag2O.
mols Ag2O = grams/molar mass = ?
mols Ag = 2*mols Ag2O
mols Ag = ?
Then g Ag = mols Ag x atomic mass Ag.
