Answer 2

2) 106.4 kg is the required answer.

Solution :

The molecular mass of lime stone (CaCo3) = 100 g

While the molecular mass of Cao = 56 g

If 100 g of CaCo3 make 56 g of CaO then 1 g of CaCo3 will make = 56/100 g of CaO

And 200000 g of CaCo3 will make =

$\frac{56}{100} \times 200000 = 106.40 \: g \: of \: CaO$
