# Thread: Calculating avogadros number from gravitational constant measurement

1. Very close together even density spheres can be used to calculate the number of nucleons involved, and thereby Avogadro's number for nucleons per gram in involved materials as follows.
R1 and R2 radiuses of the spheres of the measurement (Cavendish experiment). r distance between the spheres measured or calculated for the individual measurement r=(G*M1*M2/F)^0,5. M1 M2 the masses of spheres used and G the resulting gravitation constant of each experiment. From these the proportional distances p1=r/R1 and p2=r/R2. Next the volumetric reduction coefficients k1=3/2*p1^2-3/4*(p1^3-p1)*ln((p1+1)/(p1-1)) and k2 the same way. These give Avogadro's number for nucleons per gram of mass NAn=c^2/(2*1000*G*k1*k2).
I would be forever thankful for any experiment results, since they are hard to obtain whit no up to date university connections. The results are probably equally much off as the technic ampere, and NAn get values < 5,9*10^23. Below calculator for NAn.
