Calculate the number of atoms in 1.0 mole of o2

Number of molecules = moles x avogadros constant so 1 x 6.02x10^23 = 6.02x10^23

O2 has two atoms therefore you times your answer by 2 making it

= 1.204x10^24

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
