Lithium is the lightest metal. Its density is 0.53 gram/cm3 .
Carbon exists in at least 4 different 'allotropes',
with the following densities:
Amorphous carbon (charcoal, soot, etc.) . . 1.8 to 2.1
Buckminsterfullerene C60 . . . . . . . .. . . . . . 1.69
Graphite (pencil lead, dry lubricant, etc.) . . 1.9 to 2.3
Diamond. . . . . . . . . . . . . . . . . . . . . . . . . . . 3.50 to 3.53
So if you have equal volumes of lithium and carbon, the carbon has
at least 3.19 times the mass of the lithium, and possibly as much as
6.66 times its mass.

Does a planet with greater mass have greater surface area?
A planet with a greater mass does not necessarily have greater surface area than one with less mass. The planet could be made of denser material and have a smaller surface area. Mass doesn't always mean volume.
Is the mass of an electron less than or greater than 1?
It is less than 1 kilogram, certainly.
Is the mass of the compound equal to greater than less than or either greater than or less than the sum of the masses of the individual elements?
Equal, for all practical purposes, due to conservation of mass. In theory, it can be slightly less, but the effect is insignificant. Do some reading on "mass deficit" for more information; but briefly, energy can escape during a chemical reaction, and this energy has some mass.
What element has an atomic mass greater than 75 but less than 79?
Element 34, Selenium, has an atomic mass of about 78.96.
Which is greater a kilo or a jewel?
Jewels come in several sizes, but usually their mass will be less than a kilogram.Jewels come in several sizes, but usually their mass will be less than a kilogram.Jewels come in several sizes, but usually their mass will be less than a kilogram.Jewels come in several sizes, but usually their mass will be less than a kilogram.
