Step-by-step explanation:

Potassium oxide will combine with carbon dioxide to produce potassium carbonate according to the following equation:

K₂O + CO₂ ----> K₂CO₃

According to the coefficients of the equation, 1 mol of K₂O (when reacting with excess carbon dioxide) will produce 1 mol of K₂CO₃. The molar ratio between K₂O and K₂CO₃ is 1 to 1. We can use that relationship to find the number of moles of K₂CO₃ that will be produced by the combination of 4.5 moles of K₂O with excess CO₂.

1 mol of K₂O : 1 mol of K₂CO₃ molar ratio

moles of K₂CO₃ = 4.5 moles of K₂O * 1 mol of K₂CO₃/(1 mol of K₂O)

moles of K₂CO₃ = 4.5 moles

Answer: 4.5 moles of potassium carbonate will be produced.
