<span>At STP 1 mol of an ideal gas has a volume of 22.4 L.
We assume (from the question) that the methane has an ideal behavior.
Hence if 1 mole of an ideal gas ccupies a volume of 22.4 L
Then 0.75 mole occupies X
Hence X * 1 = 0.75 * 22.4
X = 16.8L</span>
423 psi
Hope this helps and GOOD LUCKKK :)))

Answer:
3 valence electrons
Explanation:
Because aluminum has three, that means three fluorines can bond. The make the formula AlF3, also known as aluminum trifluoride. Each of the fluorine atoms gets an electron to fill their shell, and the aluminum loses three, giving it a filled shell too (remember, aluminum has three extra electrons).
