Answer:
M.wt of CaCO
3
=100
number of moles of CaCO_3 present in 50gm =
100
50
=0.5
1 mole of CaCO
3
= 3 moles of O
2
0.5 moles of CaCO
3
has 1.5 moles of oxygen.
1mole=6.022∗10
23
particles
∴ 50g of CaCO
3
=1.5∗(6.022∗10
23
)=9.035∗10
23
oxygen atoms.

Explanation:
molar mass of CaCO3 = 100 u
moles of calcium carbonate = 50/100 = 0.5
in 1 mole calcium carbonate, 1 mole Ca is present
in 0.5 mole , Ca = 0.5 mole
1 mole Ca = 6.022*10^23 atoms ofcalcium
0.5moles Ca = 3.011*10^23 calcium
similarly, CO3 2- = 3.011*10^23 ions
