When dividing, the powers of 10 are subtracted.
Example:  4.2x10^{6}  2.1x10^{2}  = 2x10^{4} 
To calculate the density of an object the following equation is used:
D = M/V
where D = density, M = mass, and V = volume.
 Calculate the density of the Sun.
mass = 1.989x10^{33}g
volume = 1.41x10^{33} cm^{3}
 Calculate the density of a white dwarf star.
mass = 1x10^{33} g
volume = 5.23x10^{26} cm^{3}
 Calculate the mass of a neutron star.
density = 6.55x10^{14} g/ cm^{3}
volume = 3.05x10^{18} cm^{3}
CHALLENGE:
A teaspoon has a volume of 1.5 cm^{3}. Using the density in
problems 7, 8,
and 9 above, determine how much mass would be contained in 5 teaspoons of
each object.
