###### Problem Details

For the reaction, calculate how many moles of the product form when 0.021 mol of O2 completely reacts. Assume that there is more than enough of the other reactant.

2Ca(s) + O2 (g) → 2CaO(s)

Part B

For the reaction, calculate how many moles of the product form when 0.048 mol of O2 completely reacts. Assume that there is more than enough of the other reactant.

4 Fe (s) + 3O2 (g) → 2Fe2O3 (s)
