Answer:
0.375 mols
Explanation:
- Relative atomic mass Ar of C=12×1=12
- Relative atomic mass Ar of O=16×2=32
- Realitive formula mass Mr is 12+32=44
mol:mass
1 : 44
x :16.5
cross multiply and get the answer
Answer:
The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.

Explanation:
Using the Combined Gas Law, which is:
<em>(With </em>
<em>being initial pressure, volume and temperature; and</em>
<em />
<em> being the new values)</em>
<em />
We can move the units around in order to solve for 
, which would look like this:
Then we convert the Celsius temperature to Kelvin:
°
= 
° = 
And now, we plug in all of the values and solve, with volume remaining as a constant:
<em>or </em>
The tool that can be used is a seismograph.
