Theres this really good math site called e621
I recommend you try using it sometime, it has helped a lot of kids with their math homework in the past :)
The formula for the force between two objects is F=GMm/r^2 where M and m are the masses of the two objects, G is a constant, and r is the distance between them. Solve the formula for m
.m=Fr^2/GM
m=r^2/FGM
m=GM/Fr^2
m=FGM/r^2
