- 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
