Question

Using the pressure from the previous question (pressure = 6.392 Hg) and seeing that you will be using 0.1504 g of CaCO₃ in a room that is 25 degrees Celsius, what is the theoretical yield of carbon dioxide gas? Give the answer in mL.

A) 45.12 mL
B) 56.40 mL
C) 36.48 mL
D) 51.28 mL

Answer 1

To calculate the theoretical yield of carbon dioxide gas, we need to find the number of moles of CaCO₃ and use stoichiometry to convert moles of CaCO₃ to moles of CO₂. However, since the balanced equation is not provided, we cannot calculate the exact answer.

Step-by-step explanation:

To calculate the theoretical yield of carbon dioxide gas, we need to find the number of moles of CaCO₃ reacted and use stoichiometry to convert moles of CaCO₃ to moles of CO₂. Since the equation is not provided, we cannot calculate the exact answer. However, assuming the balanced equation is:

CaCO₃(s) → CaO(s) + CO₂(g)

and the molar mass of CaCO₃ is 100.09 g/mol, we can calculate the number of moles of CaCO₃:

moles of CaCO₃ = mass of CaCO₃ / molar mass of CaCO₃ = 0.1504 g / 100.09 g/mol

Once we have the number of moles of CaCO₃, we can use stoichiometry to determine the number of moles of CO₂ produced. However, since we don't have the balanced equation, we cannot calculate the exact answer.
