Question

100 grams of caco3 Rises 56 grams + 45 grams of sea water in the above reaction what is the volume of Co2 is liberated when grams of calcium carbonate heated​

Answer 1

Chemical reaction involved is:

CaCO  

3

​  

→CaO+CO  

2

​  

 

Molar mass of CaCO  

3

​  

=40+12+16×3=100 g

According to the balanced reaction 100 g of CaCO  

3

​  

 produces 1 mol of CO  

2

​  

 i.e. 22.4 L at STP.

∴50 g CaCO  

3

​  

 will produce  

100

22.4

​  

×50=11.2 L CO  

2

​  

 at STP.
