    The moles of oxygen gas that form when 4.64 g of solid silver oxide decomposes is calculated as below

    calculate the moles of Silver oxide that decoposed

    moles = mass/molar mass

    = 4.64 g/232 g/mol = 0.02 moles

    write the balanced reacting equation

    2Ag2O = 4 Ag + O2

    from the equation above the reacting ratio between Ag2O to O2 is 2:1, therefore the moles of O2

    = 0.02 x 1/2 = 0.01 moles of oxygen
