Energy Levels of Electrons. As you may remember from chemistry, an atom consists of electrons orbiting around a nucleus. ... They are restricted to orbits with only certain energies. Electrons can jump from one energy level to another, but they can never have orbits with energies other than the allowed energy levels.

Explanation:
There are two compounds that could have molecular formula of C2H6O, they are ethanol and methoxy methane (trivial name: methyl ether). The structures of the two compounds are shown in the image attached as obtained from quora.
The boiling point of methoxymethane is -24.8°C while that of ethanol is about 78.5°C. The reason for the high boiling point of ethanol is the presence of intermolecular hydrogen bonding leading to a stronger intermolecular interaction compared to methoxymethane molecules held together only by very weak dispersion forces.
Answer:
1.605cm = 4 significant figures
16.050cm = 4 significant figures
16.050cm = 4 significant figures
12 + 12.5 + 125 = 149.5 = 4 significant figures
1.62 × 10^3/2.8 × 10^-5 = 1620/0.000028 = 11 significant figures
