calculate the number of nucleons in 10cm3 flourine gas

Answer 1

I worked this below earlier today.
mols F2 gas = 10 cc x (1 mole/22,400 cc) = ?
Twice that is moles F atoms.
Number of moles of F atoms x 6.02E23 = number of F atoms.
Number of F atoms x 19 nucleons/atom = number of nucleons if you have F-19.
