Consider a 170 pm-diameter carbon atom with a mass of 1.99 × 10^-26 kg. Find how dense it is.

Determine the mass density (The ratio of a substance's mass to the volume it occupies) in SI units of a solid object weighing 0.0143 kg and occupying 245 cm³ of space.

In the laboratory, a certain liquid that is heavier than water was synthesized and it has a mass of 70 mg. This particular liquid has a density 10% higher than that of water. If this certain liquid would be frozen into a cube, what would be its side length?

If a ceramic coffee mug, with a height of 10.0 cm and a diameter of 8.00 cm, had the same density as a neutron or a proton, what would be its approximate mass?

If a piece of metal has a measured mass of 250 grams and a volume of 50 cm³, determine the density of the metal to the appropriate number of significant figures.
