Answer: 228.8 g of O2 are produced
Work:
1) Write the give balanced chemical equation:
2H2O2 → 2H2O + O2
2) molar ratios
2 mol H2O2 : 2 mol H2O :1 mol O2
3) proportion with the unknown quantity number of moles of O2:
x 1 mol O2
---------------------- = -----------------------
14.3 mol H2O2 2 mol H2O2
4) Solve for x:
x = 1 mol O2 * 14.3 mol H2O2 / 2 mol H2O2 = 7.15 mol O2
5) Use the molar mass of O2 to convert 7.15 mol O2 to grams
molar mass of O2 = 2 * atomic mass of O = 2 * 16.00 g/mol = 32.00 g/mol
molar mass = mass in grams / number of moles
=> mass = molar mass * number of moles
mass of O2 = 32.00 g / mol * 7.15 mol = 228.8 g
Answer: 228.8 g
