The part of the system that is designated as surroundings is;
Inside the fume hood
<h3>Thermodynamics Systems</h3>
We are told that the chemist is performing a reaction under a fume hood.
Now, in thermodynamics there is what we call homogenous and heterogenous systems. Each of those systems have what we call surroundings, system and boundary.
Now, everything that is around a system is referred to as a surrounding while boundary is simply defined as everything that is external to the system.
Now, in this case since the chemist is performing the chemical reaction under a fume hood, then the boundary will be everything outside the fume hood while the surroundings will be inside the fume hood.

0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.
<h3>Total atoms in a compound</h3>
Given the following parameters
- Mass of Cu2s = 32.8 grams
Get the number of moles
Moles = 32.8/159.16 g/mol
Moles of Cu2S = 0.240moles
Since 1 molecule of atom = 6.02 * 10^23 molecules
Hence 0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.
