The quantity called mass density is the mass per unit volume of a substance. What are the mass densities in basic SI units of the following objects?a. A 215 cm³ solid with a mass of 0.0179 kg.

The Near Earth Asteroid Rendezvous (NEAR) spacecraft, after traveling 2.1 billion km, orbited the asteroid Eros with an orbital radius of about 20 km. Eros is roughly 40km x 6km x 6km. Assume Eros has a density (mass/volume) of about 2.3 x 10³ kg/m³ .

(a) If Eros were a sphere with the same mass and density, what would its radius be?

A wooden cylinder has a radius of 3.5 cm and a height of 6 cm. If the mass is 161 g, what is the density of the wooden cylinder?

Copper has a density of 8.96 g/cm³. If a single copper atom as a mass of 1.055×10^-25 kg, what is the volume of a copper atom?

A standard baseball has a circumference of approximately 23 cm. If a baseball had the same mass per unit volume (see Tables in Section 1–4) as a neutron or a proton, about what would its mass be?

The density of an object is defined as its mass divided by its volume. Suppose a rock's mass and volume are measured to be 6 g and 2.8325 cm³. To the correct number of significant figures, determine the rock's density (mass/volume).
