The equation for the catalytic decomposition of hydrogen peroxide is:
2H2O2(aq)→2H2O(l)+O2(g) 2\text{H}_2\text{O}_2(\text{aq}) \rightarrow 2\text{H}_2\text{O}(\text{l}) + \text{O}_2(\text{g}) 2H2O2(aq)→2H2O(l)+O2(g)An aqueous solution containing 1.36 g of hydrogen peroxide (H2O2\text{H}_2\text{O}_2H2O2) is completely decomposed in the presence of a catalyst.
Calculate the maximum volume of oxygen gas in dm3\text{dm}^3dm3, measured at room temperature and pressure, that could be produced in this reaction.
(relative formula mass: H2O2=34\text{H}_2\text{O}_2 = 34H2O2=34, 1 mol of any gas at room temperature and pressure occupies 24 dm3)
