i'm not all that great at chemistry, but If no one else comes to help, i'd do the first part like this:
$$9.27x10^{-26} g \times \frac{ cm^3 }{ 7.87 g } =  ? cm^3$$this way the units of grams cancel out, and all that is left is cm^3 which is a measurement unit of volume. 

as for Part B, there is going to be an equation from your notes or books that discusses the distance between electrons.

How would you solve (B) @DemolisionWolf

@Christos for part B, there needs to be an equation for electron distance or something in you book i'd imagine. chemistry isn't a strength of mine
