  • Thermal Decomposition

    This is the mass of one mol. Therefore, all we do now is: (1 mol/221.13 g)(1 g) = 0.00452 mol b) moles of CuO produced: We determine the molar mass of CuO and then do the same thing we did above: Molar mass of CuO is 79.55 g.

  • Balancing given redox reaction and calculating percent yield

    expected amount of CuO = 0.01944 mol CuO or in grams, mass of expected CuO = 0.01944 x 79.54 g/mol(molar mass) =1.546 g CuO now, %yield = 9actual yield/theoretical yield) *100 = (1.235 / 1.546)*100 = 79.87% yield.
