Answer:
B 22.4 litres
Explanation:
equation CACO3----------> CAO + co2
given that caco3 is 100 gram it means 1 mole (moles=given wt/ molecular wt)
according to the equation 1mole caco3 produces 1mole co2
so amount of co2 is 1 mole or 22.4 litres (1mole= 22.4 litres at NTP)
(NOTE ACTUALLY AT NTP VOLUME MOF ONE MOLE IS 22.7 LITRES )
The volume in litres of CO2 liberated at STP, when 10 g of 90% pure limestone is heated completely.
