Answer:
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
