Calcium carbonate decomposes upon heating to produce calcium oxide and carbon dioxide according to the equation:

CaCO3→CaO+CO2 \text{CaCO}_3 \rightarrow \text{CaO} + \text{CO}_2 CaCO3​→CaO+CO2​

What mass of calcium carbonate would be needed to produce 14.0 g of calcium oxide? (Relative atomic masses: Ca=40\text{Ca} = 40Ca=40, C=12\text{C} = 12C=12, O=16\text{O} = 16O=16)
