Question

What is the volume of 3×10^8 molecules of CO2 in ml.??

Answer 1

1 mole CO2 is equivalent to 22400 ml CO2
again 1 mole CO2 contains 6.022× 10^23 CO2 molecules.
so,
6.022×10^23 molecules of CO2 equivalent to 22400 ml CO2

or, 3× 10^8 molecules of CO2 equivalent to (22400÷6.022÷10^23)×3×10^8 ml CO2
=1.116 × 10^(-11) ml CO2
