finlep [7]
<span>since the vast majority have never been studied in the laboratory and have only been detected by analysis of their nucleic acids in samples from the environment.

andre [41]

Answer:

0.1631309437 g/cm^3

With this formula, we can calculate the density of the object:

ρ = \frac{22.3g}{136.7cm^3}

=0.1631309437 g/cm^3
