The density of a planet can be approximated from its radius and estimated mass. Calculate the approximate average density, in grams per cubic centimeter, of (a) Jupiter, which has a radius of about 7.0 × 10 4 and a mass of 1 .9 × 10 27 k g ; ( b ) Earth, radius of 6 .4 ×10 3 km and mass of 5.98 × 10 24 kg; and ( c ) Saturn, radius 5 .82 × 10 4 km and mass of 5.68 × 10 26 kg . The volume of a sphere is 4 π r 3 / 3 where r = radius . How does the density of each planet compare to that of wate r ?

ohing Quantitative Relationships

The specific heats and atomic masses of 20 of the elements are given in the table below. Use a
graphical method to determine if there is a relationship between specific heat and the atomic mass.
a.
b.
C.
d.
e.
If your graphs revealed
relationship between specific heat and atomic
revealed a mathematical
mass, write down an equation for the relationship.
Comment on the usefulness of the determination of
specific heat as a method for identifying an
element. Would specific heat alone give you much
confidence with regard to the identity of the
element? If you think measurement of another
property would be needed to support an
identification, what property would you measure
and why?
The elements listed in the table are all selected
metals. The values for nitrogen, oxygen, fluorine
and neon are 1.040, 0.918, 0.824 and 1.030 J/g K
respectively. Do these elements fit your equation?
