Mass if `CO_(2)` Produced on heating 20g of 40% pure limestone :-

A

8gm

B

8.8gm

C

3.52gm

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(CaCO_(3),to, CaO,+CO_(2),),( 100g , ,56g , 44g,):}`
wt of pure limestone ` = (20xx40)/(100)=8gm`
100 gm pure `CaCO _(3)` produce ` to 44g CO_(2)`
8 g pure `Caco_(3)` produce to `3.52 g CO_(2)`
