Explanation / Answer

Number of moles of CaO = 545 g / 56.077 g/mol = 9.72 mole

from the balanced equation we can say that

1 mole of CaO produces 1 mole of CO2 so

9.72 mole of CaO will produce

= 9.72 mole of CaO *(1 mole of CO2 / 1 mole of CaO)

= 9.72 mole of CO2

Therefore, the number of moles of CO2 produced would be 9.72
