A 0.500 g sample containing Ag₂O and inert material is heated,causing the silver oxide to decompose according to the following equation:
2 Ag₂O(s) → 4 Ag(s) + O₂(g)
If 13.8 mL of gas are collected over water at 27°C and 1.00 atm external pressure,what is the percentage of silver oxide in the sample? The partial pressure of water is 26.7 mm Hg at 27°C.
