## Black Holes - Page 18

When dividing, the powers of 10 are subtracted.

To calculate the density of an object the following equation is used:
D = M/V
where D = density, M = mass, and V = volume.

Example: | 4.2x10^{6}------- 2.1x10 ^{2} | = 2x10^{4} |

- 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}

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.
