Using the ideal gas law, 0.0025 moles of oxygen gas are created when 2H2O2 (aq) reacts with 2H2O (l) and O2 (g).
Given that, according to the balanced chemical equation, hydrogen peroxide, H2O2, breaks down to produce water and oxygen gas:
2H2O2 (aq) -> 2H2O (l)+ O2 (g)
Ideal temperature (t) = 295.15 K and
pressure (p) =1 atm
Volume of oxygen gas (v) = 0.061 L
R = 0.0821
From the ideal gas law equation = pv= nRt
n = pv/Rt = 1 x 0.061/0.082x 295.15
n = 0.0025moles
Hence the number of moles produced from the above reaction is 0.0025
