Question

3. 1.0 mole CO2 contains
a. 6.022 x 10-23 atoms of carbon
c. 6.022 x 10-23 molecules of CO2
b. 6.022 x 10-23 atoms of oxygen
d. 3 g atom of CO2​

Answer 1

Answer:

One mole of CO2= one mole of C =6.02×1023 atoms of carbon.

One mole of CO2= two moles of O =2×6.02×1023=12.04×1023 atoms of oxygen.

One mole of CO2=   6.02×1023 molecules of CO2

Note: 6.02×1023 is Avogadro's number and represents number of atoms/molecules present in one mole of substance.
