The diameter of a hydrogen nucleus is 1.0 X 10 -3 pm and its mass is 1.67 X 10 -24 g. What is the density of the nucleus in grams per cubic centimeter? Assume the nucleus is a sphere with volume = 4/3pie r3.

Convert 1E-3 pm to cm and take half of that to find the radius.
Use the volume of a sphere to calculate volume (note it's pi and not pie).
Then density = mass/volume.
