To determine the number of moles of O₂ produced from 32.0 grams of hydrogen peroxide, we first need to write out the balanced chemical equation for its decomposition: 2 H2O2 → 2 H2O + O2 From this equation, we can see that for every 2 moles of hydrogen peroxide, 1 mole of oxygen gas (O2) is produced. Using the molar mass of hydrogen peroxide (34.01 g/mol), we can calculate the number of moles present in 32.0 grams: 32.0 g H2O2 × (1 mol H2O2/34.01 g H2O2) = 0.941 mol H2O2 Since the mole ratio between H2O2 and O2 is 2:1, we can divide the number of moles of H2O2 by 2 to get the number of moles of O2 produced: 0.941 mol H2O2 ÷ 2 = 0.470 mol O2 Therefore, the answer is B) 0.470 mol of O₂ will be produced.
