Best Answer

.183mol CaO

Ca is your limiting reactant, O2 is your excess reactant.

thus 7.34g Ca = .183mol Ca, since the balanced reaction is 2Ca + 1 O2 -> 2 CaO, 1 mol Ca = 1 mol Cao and .183mol CaO is produced.

4.25 mole CaCO3 (3 mole O/1 mole CaCO3)(6.022 X 10^23/ 1 mole O)(1 mole O atoms/6.022 X 10^23)

= 12.8 moles of oxygen atoms

2Ca + O2 --> 2CaO

0.016 moles O2 (2 mole CaO/1 mole O2)

= 0.032 moles calcium oxide produced
