I Hope this is helpful for u.....

Molecular mass of calcium carbonate = 40 + 12 + 48 =100g

 1 mole of Calcium carbonate contains – 3 mole of oxygen atoms

100 g of Calcium carbonate contains - 3 X 6.022 X 1023 oxygen atoms

300g of Calcium carbonate contains - How many oxygen atoms?
= 300 X 3 X 6.022 X 1023/ 100 = 54.205 X 1023 oxygen atoms


Crisella: Thank u
Renugautam: ur welcome
