Question

Calculate the number of ions number of oxygen atoms and total charge in 3 grams 32 -

Answer 1

Explanation:

Molar mass of carbonate ions = 60 g/mol

mass of carbonate ions = 3 g

Moles of carbonate ion =\frac{3 g}{60 g/mol}=0.05 mol

Number of ions =0.05\times 6.022\times 10^{23}=3.011\times 10^{22} ions

In 1 ion there are 3 atoms of oxygen

Number of oxygen atoms =3\times 3.011\times 10^{22} = 9.033\times 10^{22} atoms

Charge in 1 ion = 2-

Charge on 3.011\times 10^{22} ions of carbonate:
