<span>The notion of hybrid orbitals was "invented" by Linus Pauling in 1931 to explain the observed geometry of mostly organic molecules. Today, we find that hybrid orbitals are pretty much confined to the central atoms found in the second period of the periodic table. Periods 3 and up .... not so much.
(a) H2O ..... O is the central atom, tetrahedral, sp3 hybridization
(b) PBr5 .... P is the central atom, maybe sp2 for the three equatorial bonds *
(c) COCl2.. C is the central atom, trigonal planar, sp2 hybridization </span>

Answer:
47.3 ml
Explanation:
The graduated cylinder is shown in the image attached.
Now we have to take a good look at the cylinder, the lines between 45 and 50 are 46, 47, 48 and 49. Even though the points in between two lines weren't graduated but we can intelligently guess the correct volume by observing the upper meniscus of the liquid. Hence the answer.
