We can plug this in the the equation 
row = nA/VcNa
where ro can be determined by the mass and volume
a = 2rt(2)* atomic Radius]]> 2020-09-15 17:38:37 UTC https://padlet.com/grunenfe/1pqxh49fz93y9pqm/wish/748966332 https://padlet.com/grunenfe/1pqxh49fz93y9pqm/wish/748967122 1. Weigh the sample
2. Calculate the volume of sample (2.54^3 cm^3)
3. Calculate the density mass/volume
4. Divide density by 4*atomic mass, multiply by avogadro's number, take inverse of result
5. Result above is volume of cell, 
a = Vc^1/3
