Question

According to the following reaction, how many moles of calcium carbonate are necessary to form 0.906 moles carbon dioxide?

calcium carbonate (s) calcium oxide (s) + carbon dioxide (g)

Answer 1

0.906 moles of calcium carbonate needed to produced 0.906 moles of carbon dioxide.

Step-by-step explanation:

Given data:

Moles of carbon dioxide produced = 0.906 mol

Moles of calcium carbonate needed = ?

Solution:

Chemical equation:

CaCO₃ → CaO + CO₂

Now will compare the moles of carbon dioxide with calcium carbonate:

CO₂ : CaCO₃

1 : 1

0.906 : 0.906

So 0.906 moles of calcium carbonate needed to produced 0.906 moles of carbon dioxide.
