Here's the information you need:

#### Explanation:

- The balanced chemical equation
- The molar mass of
#"CaCO"_3# - The molar ratio of
#"CaO"# to#"CaCO"_3# - The molar mass of
#"CaO"#

Your strategy has four steps:

- Write the
**balanced chemical equation**. - Use the
**molar mass**of#"CaCO"_3# to calculate the moles of#"CaCO"_3# . - Use the
**molar ratio**of#"CaO"# to#"CaCO"_3# from the equation to calculate the moles of#"CaO"# . - Use the
**molar mass**of#"CaO"# to calculate the mass of#"CaO"# .

Your answer should be about 2.6 kg of
