Silver oxide is used in small batteries called button batteries (Figure below). It decomposes upon heating to form silver metal and oxygen gas.

Question

2Ag2O(s) → 4Ag(s) + O2(g)
How many moles of silver are produced by the decomposition of 4.85 g of Ag2O?

Answer 1

mols Ag2O = grams/molar mass = ?

Using the coefficients in the balanced equation, convert mols Ag2O to mols Ag.
