Calculate the number of co2 molecules in 4.22×10−2 mole of co2.

1 mole CO2 6.02x10²³ molecules
4.22x10⁻² mole ??

4.22x10⁻² x ( 6.02x10²³ ) / 1 => 2.540x10²² molecules

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
