Question

An astronomer finds that a meteorite sample has a mass of 15.6 g along with an apparent mass of 9.2 g when submerged in water. find the density of the meteorite?

Answer 1

Answer:

Density of meteorite = 2.44 g/cm³

Explanation:

Apparent mass = Mass of solid - Mass of water displaced

Mass of water displaced = Mass of solid - Apparent mass

                                         = 15.6 - 9.2 = 6.4 g

Density of water = 1 g/cm³

Volume of water displaced $=1\times 6.4=6.4cm^3$

Volume of meteorite = Volume of water displaced = 6.4 cm³

$\texttt{Density of meteorite}=\frac{\texttt{Mass of meteorite}}{\texttt{Volume of meteorite}}=\frac{15.6}{6.4}=2.44g/cm^3$

Density of meteorite = 2.44 g/cm³
