Question

Estimate the density of the Moon.

a) 2 - 3 g/cm³
b) 3 - 4 g/cm³
c) 4 - 5 g/cm³
d) 5 - 6 g/cm³

Answer 1

To estimate the density of the Moon, calculate its mass and volume and then divide the mass by the volume.

Step-by-step explanation:

The density of an object can be calculated by dividing its mass by its volume.

In this case, we can use the given information to estimate the density of the Moon.

The Moon has a mass of 1.6 × 1022 kg and a diameter of 1948 km.

We can calculate the volume of the Moon using the formula for the volume of a sphere: V = (4/3)πr3, where r is the radius of the Moon.

Since the diameter is given, we divide it by 2 to get the radius.

Now, we can calculate the density of the Moon by dividing its mass by its volume.
