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
