at stp conditions, 0.25 moles of co2(g), h2(g), nh3(g)
1. will contain the same number of molecules
2. will contain the same number of atoms
3. will occupy the same volume
4. will have the same g. f.w

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
