Question

What is the mass of group of test tube when it will filled by a lot of nucleus of atom?

Answer 1

The density (mass/volume) of a nucleus is extremely high: about 2.3 × 1017 kg/m3 (according to ). That's about 100 trillion times more dense than liquid water, which is 1,000 kg/m3.

Let's say the dimensions of a matchbox are about 4 cm by 5 cm by 1.5 cm. Then the volume of a matchbox is about 30 cubic centimeters, or 3 × 10-5 cubic meters. If we packed a matchbox full of material with nuclear density, its mass would be (3 × 10-5 m3) × (2.3 × 1017 kg/m3) = 6.9 × 1012 kg. That is really heavy--almost 7 billion metric tons. It's comparable to the mass of a neutron star, with a radius of a little less than a kilomete
