A sample of Nitrogen gas has volume of 17.5 L at STP. How many moles ofN2 are present?

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.

i'm pretty sure it is letter c.) car

i'm wiling to try and you : )
