Answer: 4.72 x 10^22 atoms

Explanation:

MM of CO2 = 12 +(16 x 2) = 12 +32 = 44g/mol

44g of CO2 contains 6.02x10^23 atoms

Therefore, 3.45g will contain = (3.35 x 6.02x10^23) / 44 = 4.72 x 10^22 atoms

Answer:

Number of moles = Mass / Molar mass

                              = 3.45 /44

                              =0.078 mole

hence, the number of atoms = 0.078* 6.02*10∧23

                                                 =4.695E28 atoms
