Calculate number of CO2 molcules in 2.30*10^-2 mole CO2.

Calculate number of CO2 molcules in 2.30*10^-2 mole CO2.

Solutions

Expert Solution

1 mole of CO2 have 6.02 X 1023 molecules of CO2      [From Avogadro constant]

Then, the number of molecules in 2.3 X 10-2 mole of CO2 = 2.3 X 10-2 X 6.02 X 1023

                                                                                                                       = 13.846 X 1021 = 1.3846 X 1022 molecules.
