Helium is not found. That is 8 molecules of carbon, 10 Hydrogen, 4 nitrogen, and 2 Oxygen. I think...Hope this helps.
Answer:
We will derive the combined gas equation from the law of Gases
Boyle's law
P∝1/V
PV=Constant
Charles law
V∝T
Avogadro's Law
V∝n
By combining these three equations we get the combined gas equation
PV=nRT
V=nRT/P
If n=1 mole
V=RT/P
By putting the value of R, T, and P in the above equation we can calculate the volume of the gas at STP.
The answer is 297.14 g/mol
The atom that has 7 valence electrons is A. fluorine.
It is in the halogens group.
It needs 1 more electron to become stable, therefore, it is highly reactive.
