Calculate the number of ions and total charge in 3 gram CO3^2-

Given, Mass of carbonate = 3g
As we know,
The molar mass of carbonate ion is 60 g per mole.
This means mass of 1 mole of carbonate ions = 60 g
1 mole = 6.022×1023
The number of ions in 3g = 0.05×6.022×1023 = 0.3011×1023
In a carbonate ion there are 3 oxygen atoms and one carbon atom
Number of carbon atoms in 3g of carbonate = 1 × 0.3011×1023 =0.3011×1023
Number of oxygen atoms in 3g of carbonate = 3 × 0.3011×1023 =0.9033×1023
And the charge on carbonate ion is -2
Therefore total charge on 3g of carbonate ions = (-2) × 0.3011×1023 =-0.6022×1023
