The volume in litres of `CO_(2)` liberated at STP when 10 grams of 90% pure limestone is heated cmpletely is

Text Solution

Verified by Experts

The correct Answer is:
d
`underset((100g))underset(1"mole")(CaCO_(3)) to underset("22.4 litre in STP")(CaO)+CO_(2)(g)`
`therefore 100g CaCO_(3)-=22.4L CO_(2) "At STP"`
`therefore "9g "CaCO_(3)=(22.4)/(100)xx9L CO_(2)"at STP"`
`"=2.016L "CO_(2)" at STP"`
