Question

Calculate the average density of the following astronomical body: Pluto.

Pluto =.kg/m3

Where does the value fit among those listed in the table below? Look up the density of a typical rock, such as granite in another source and compare the density of Pluto to it

Densities of Some Common Substances at Standard Temperature (0°C) and Pressure (Atmospheric) p (kg/m3) Substance Substance Air 1.29 Ice 2.70 x 103 Aluminum Iron 0.879 x 103 Benzene Lead 8.92 x 103 Copper Mercury Ethyl alcohol 0.806 X 103 Oak 1.00 X 103 Fresh water oxygen gas 1.26 x 103 Glycerin. Pine 19.3 X 103 Gold Platinum 1.79 x 10 Sea water Helium gas 8.99 x 10 Hydrogen gas Silver p (kg/m3) 0.917 x 10 7.86 x 10 11.3 x 103 13.6 x 103 0.710 x 10 1.43 0.373 x 103 21.4 X 103 1.03 x 10 10.5 x 10

Explanation / Answer

mass of pluto = 1.31*1022 kg

Volume of pluto = 6.4*1018 m3

Density = m/V = 1.31*1022/6.4*1018 = 2046.875 kg/m3

Comparing this to the density of granite

dp/dg = 2046.875/2750 = 0.744

hence dp = 0.744dg

Where dp is density of pluto

dg is density of granite
