Determine the weight of the body, balanced on the beam scale with a set of weights: 50g; 10g; 5g; 500mg; 20mg.

So, to find the mass of a body balanced on the scales, you just need to add the masses of all the weights that balanced it:
50g + 10g + 5g + 500mg + 20mg = 65.52g.
Let’s translate into SI:
65.52g = 0.06552kg
