Chemistry is concerned with:
1) Composition
The composition of matter helps determine how it will behave chemically and physically, and is studied in chemistry
2) Structure
The structure of a certain element or compound also governs how the substance behaves, making it another vital aspect of chemistry
3) Behavior
The behavior of substances is studied in order to have explanations presented for it, expanding our understanding.
Answer:
Earth is located in the milky way galaxy
Remember that as per the law of ideal gases the number of molecules of a gas is proportional to the volume, which means that at the same temperature and pressure, the same amount of molecules will have the same volume.
You can deduct that from pV = nRT
From there if p, and T are constants:
V = (a constant) * n
So, the same number n, will give the same number V.
Then, 3.0 molecules of H2(g) will have the same volume that 3.0 molecules of any other gas, under same pressure and temperature, assuming ideal gases.
So, the answer is the third option, 3.0 L of CH4(g).
