The answer is (2) low temperature and high pressure so oxygen gas behave least like an ideal gas :)))

Answer:
The answer to your question is: Volume = 29.79 cm³
Explanation:
Data
Density of gold = 19.3 g/cm3
Mass = 575 grams
Formula
density = mass / volume
Volume = mass/density
Volume = 575 g / 19.3 g/cm3
Volume = 29.79 cm³
Blank 1: polar
The difference in electronegativity between N and H causes electrons to preferentially orbit N, making the bond polar.
Blank 2: trigonal pyramidal
There are four “things” attached to N - 3 H’s and 1 lone pair of electrons. The four things together are arranged into a tetrahedral formation. However, the lone pairs don’t actually contribute to the shape of the molecule per se; it’s only the actual atoms that do. The lone pair creates a bit of repulsion that pushes the 3 H’s down, creating a trigonal pyramidal shape (as opposed to a trigonal planar one).
Blank 3: polar
The molecule as a whole is also polar because the “things” around it, though arranged in a tetrahedral pattern, are not all the same. The side of the molecule with the lone pair is slightly negative, while the side with the 3 H’s is slightly positive due to the differences in electronegativity described above.
