Answer:
Explanation:
You can convert the <em>density</em> into <em>atomic density</em> using the <em>atomic weight </em>and Avogadro's number
A dimensional analysis is very helpful:
Follow the chain: g cancels with g, mol cancels with mol; at the end, what remains is atoms/cm³, which is what you want.
Use that with your data:
Answer:
Explanation:
ρ =
m
V
=
30.8 gram
34.9 cubic meter
= 0.88252148997135 gram/cubic meter
= 0.00088252148997135 kilogram/cubic meter
When wood burns, some of the mass is released as a gas. So if you were to combine the small fraction of ash with the gases released, you would get the mass of the original wood.
Most of the mass of an atom is located in the (nucleus), and most of the volume is taken up by the (electron clouds).
The ones in the parenthesis are your answers.
