Density describes how much mass is contained in a certain volume. Knowing how far apart molecules are in each state, which best ranks solids, liquids, and gasses from least dense to most dense?

Gasses are denser than liquids.
Liquids are denser than solids.
Gasses are less dense than solids.
Solids are less dense than liquids.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
