Answer 1

Answer:

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

1 mole of calcium carbonate contains 3 mole of oxygen atom.

100 gm of calcium carbonate contains 100*6.022*1023 atoms.

Explanation:

300 g of calcium carbonate contains

how many oxygen atoms?

300*3*6.022*1023/100=

54.205*1023 oxygen atoms
