Some Basic Concepts of Cherni
Calculate the number of lons number of oxygen atom and total charge in 3 gm CO,​

Answer 1

Answer:

Step-by-step explanation:

formula units =Mass of species/formula mass ×6.02×10 ^23 = 3/60×6.02×10^23=. 3.0×10^22(approx) Number of oxygen atoms =Number of formula units×3= 3.0×3×10^22= 9.0×10^22 Charge=3.0×10^22×3. 2×10^-19=9.6×10^3 coulomb

Answer 2

Molar mass of carbonate ions = 60 g/mol

mass of carbonate ions = 3 g

Moles of carbonate ion =3g/60g

=0 .05mol

Number of ions =0.5×6.022×10^23

=3.011×10^22

In 1 ion there are 3 atoms of oxygen

Number of oxygen atoms =3×3.011×10^22

= 9.033×10^22

Charge in 1 ion = 2-

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

-2×3.011×10^22

-6.022×10^22
