Answer:
1.04 mol
Explanation:
CO₂ is produced in a closed 100 L vessel according to the following equation.
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
At equilibrium, the pressure of carbon dioxide remains constant at 1.00 atm.
First, we need to conver the temperature to the absolute scale (Kelvin scale) using the following expression.
K = °C + 273.15
K = 898°C + 273.15
K = 1171 K
Now, we can find the moles of carbon dioxide using the ideal gas equation.

Answer:
4 is the best answer but incomplete.
