Dear student 
Above explanaton is incorrect
Molar mass of Caco3 = 100g 
10kg 100% pure CaCo3 = 10kg Caco3 
10kg 80% pure Caco3 = 8 kg CaCo3 
No of moles of CaCo3 = 8*1000/100
= 80 moles
1 mle of CaCo3  gives 1 mole of co2 
80 moles of CaCo3  gives 80 moles of co2 
1 mole of Co2 = 44g 
80 moles of Co2 = 80*44 
= 3.52 kg of Co2
