🤓 Based on our data, we think this question is relevant for Professor Gellene's class at TTU.

Solution: The radius of a neon atom is 69 pm, and its mass is 3.35 x 10-23 g. What is the density of the atom in grams per cubiccentimeter (g/cm3)? Assume the nucleus is a sphere with volume = 4/3πr3.

Problem

The radius of a neon atom is 69 pm, and its mass is 3.35 x 10-23 g. What is the density of the atom in grams per cubic
centimeter (g/cm3)? Assume the nucleus is a sphere with volume = 4/3πr3.

Solution

Recall: Density is given by:

We know the mass of a neon atom, 3.35 × 1023 g. For the volume, we need to calculate the volume of the atom. The volume of a sphere is given by:

where r = radius.
