<h3>The density of the proton is 2.3 x 10²⁰ g/m³.</h3><h3 /><h3>FURTHER EXPLANATION</h3>
The density of a substance is equal to the ratio of its mass and volume.

To get the density of the proton, the following steps must be completed:
1. Determine the volume of the spherical proton.
2. Calculate the ratio of the mass and the volume of the proton.
<u>STEP 1:</u> To determine the volume, the equation for the volume of a sphere must be known.

where r is 1/2 the diameter of the sphere.
Plugging in the values to get the volume in cubic meters:

STEP 2: Once the volume is known, the density can be calculated by getting the ratio of the mass (in grams) and the volume in cubic meters.

Since the least number of significant figures in the given is 2, the final answer must also only have two significant figures.
Therefore,
