Moles, molecules and atoms

You will write three small functions for the mole map: grams to moles, moles to molecules, and grams straight to atoms. The program then fills a table for four samples.

The idea. $n = \dfrac{m}{M}$, $N = n \times N_A$, and the atoms are the molecules times the atoms in one molecule. $N_A = 6.022 \times 10^{23}$.

Your tasks.

1. Make moles(m, M) return the number of moles.
2. Make molecules(n) return the number of molecules.
3. Make atoms(m, M, k) return the number of atoms in $m$ grams, with $k$ atoms in each molecule, using the two functions above.
