Find the mass of caco3 required to produce 11.2litre of CO2 ​

Answer 1

Find the mass of caco3 required to produce11.2litre of CO2

Answer 2

Answer:

The mass of CaCO₃ required to produce 11.2litre of CO₂ is equal to 50g. ​

Explanation:

The decomposition of calcium carbonate:-

On heating, Calcium carbonate decomposes to give calcium oxide and carbon dioxide.

CaCO₃  $\longrightarrow$   CaO  +  CO₂

From the above equation, we can say that one mole calcium carbonate will produce onw mole of carbon dioxide.

Given, the volume of carbon dioxide is produced = 11.2 L

22.4 L volume of any gas = 1 mole

Therefore, 11.2 Liter of carbon dioxide = 11.2/22.4 = 0.5 mole

1 mole of carbon dioxide is produced by CaCO₃ = 1 mole

0.5 mole of carbon dioxide will be produced by CaCO₃ = 0.5 mole

Molar mass of  CaCO₃  = 100g/mol

The amount of CaCO₃  = 0.5 × 100 = 50g

Therefore, the mass of CaCO₃ required to produce 11.2litre of CO₂ is equal to 50g. ​
