Answer:
2.89 g/cm^3
Explanation:
Since density equals mass over volume (or also seen as 
), simply divide 66.5 grams by 23.0 cm. This will output an answer of 2.89 g/cm^3.
Answer: <em>Hopefully this helps! sorry if not. :))</em>

<em>Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.</em>
C₀=8.10M
c₁=5.28M
v₀=1.58 L
v₁-?
n=c₀v₀=c₁v₁
v₁=c₀v₀/c₁
v₁=8.10*1.58/5.28=2.42 L
