 Homework Statement:
 Finding dimension of molecule and avagadros constant
 Relevant Equations:

Na = N/n
v = lwh
I have done all of the questions apart from c and d. For a I got the answer 2.58*10^_5 cm^3
B) 3.72*10^7 cm
But for c I don’t really know how to start. I first thought of using the formula for volume of cuboid but don’t know how that’d give the answer for the dimension.
For D, I turned the density from 890 kg m^3 to 0.89 g cm^3, found the molecular mass to be 282 and from my previous question used the volume v = 2.58*10^5 to get mass = 2.2962*10^5g from the formula p =m/v.
I’d just like to know how to do c and d, thanks for your help
