my attempt: no units for specific gravity. Density of gold in g.ml^-1 = 19.2 g/mL^-1 I have no idea how to convert to pounds per cubic foot?
4. The mass of the earth is 6.1 x 10^27 g and the radius is 6.4 x 10^6 m. What is the average density of the earth in g.mL^-1? Hint the volume of a sphere is 4/3 pie r^3 where r is the radius of the sphere.
2.6 x 10^19 g/ml^-1
5. The mass of a neutron is 1.675 X 10^-24 g. The radius is about 10^-15 m. What is the density of a neutron in g.mL-1? What assumption is being made about the structure of the neutron in this calculation?
my attempt: 4.2 x 10^ -45
assume the structure is a sphere?
Suppose you have a metal with a small volume (0.5mL) and a metal with a large volume (5.0mL). Which should give a higher percentage error if we use the water immersion method? explain.
my attempt: i would think less water would give a higher percentage error but not sure of the reasoning my guess the water not covering the metal throwing off the accuracy?
