The mass of CaO that shall be obtained by heating 20 kg of 90% pure lime stone `(CaCO_(3))` is

A

`11*2 kg`

B

`8*4 kg`

C

`10*08 kg`

D

`16*8 kg`

Text Solution

Verified by Experts

The correct Answer is:
C

`CaCO_(3)toCaO+CO_(2)`
Pure lime in 20 kg `= (20xx90)/(100) = 18 kg`
CaO produced `= (56xx18)/(100) = 10*08` kg
