Explanation:
Hope this helped!
Well, considering atoms make up everything, they clearly play a very essential role.
However, this is where we see things like balanced chemical reactions and equations. It tells us how many we need for a reaction to occur, for example 4 atoms of nitrogen, etc.
It’s the second answer. “it gets used for metabolic process & released as heat” i think.
Ideal Gas Law: PV=nRT
Divide both sides by P to isolate volume (V).
V=nRT/P
1 mol of Silicon = 28.0855 g (in average)
then
1 mol = 6.022*10^23 atoms
then
28.0855/(6.022*10^23) g/atom
4.66381*10^-23 g per atom
