CaCO3------CaO+CO2
from equation we can see that 100g of limestone produces 56g of quick lime.
from question we get that the sample is 95% pure that is 95/100×200=190g is purely limestone
since 100 g produces 56g quick lime
190g will produce 56/100×190g quick lime
=106.4g quick lime

molecular mass of caco3=100
molecular mass of cao=56
100g caco3 make 56g cao
200000g will make=56*200000/100
=112kg
for 95% =106.40kg of cao
