Answer:
Propane tanks are most commonly referred to by their water capacity volume, and propane tanks are normally filled to 80% of its water capacity. For example, a 120-gallon tank will hold approximately 100 gallons of propane when completely full. Since propane is stored in a liquid state under pressure, it needs room to
N=m/M
so n = 25g/(1.01+19.00)g/mol
n = 25g/20.01g/mol
n = 1.2493
Round to 2 sig figs
So the answer is 1.2 mol
Answer:
The brightness of a line depends on the number of electrons making that transition.
Explanation:
In atomic spectra, some electronic transitions are “forbidden” by the rules of quantum mechanics. That is, <em>some transitions are less probable than others</em>.
The brightness of a given line depends on the number of electrons making that transition.
Allowed transitions will give the brightest lines. The brightness of the other lines will vary depending on how likely the transitions are.
