This is determined by Einstein's equation E = mc2, where c = velocity of light = 3 x 108 meters/sec. So c2 = 9 x 1016. For 1 kg of mass therefore the equivalent energy is 9 x 1016 Joules, for 1 gram it is 9 x 1013 Joules.
Note units, in the SI system energy is in Joules, mass in kg, distances in meters. If you keep to these units you will get consistent results.
The above of course only holds for the complete annihilation of 1 gram or 1 kilogram of mass, which does not happen in chemical reactions, so don't try to apply it in such cases!

If by land mass you mean the surface, then 99% is habitable.
How much is the mass of a regular sized marble?
1.27 grams
Does the moon have mass?
Yes. All objects have mass, because all objects contain matter. Mass is just a measure of how much matter is contained within an object. Therefore, any object, from the smallest speck of dust to giant stars, have mass.
A person has a pumpkin that has a mass of 4.8 kilograms If 0.9 of its mass is water how much of its mass is water and how much of its mass is not water?
3.6
How much matter something contains is its?
mass
Does mass change depending a person's weight?
The weight itself is how much mass is there, so in theory the WEIGHT changes to how much mass there is.
How much mass does a proton have?
A proton has what is known as one atomic mass unit (AMU) neutrons also weigh this much but electrons weigh much much less.
What does mass weigh?
That depends on how much mass there is, how much other mass is nearby, and how far apart the two of them are. If there's no other mass anywhere nearby, then it weighs almost zero.
What is the mass of talc Not the specific gravity but the mass?
Mass is an extrinsic property... that is, it matters very much how much talc there is. Your question makes no sense.
How much does the sun have mass?
The suns mass is 332,950 earths.
How much mass in a proton?
A proton has a mass of 1 AMU (one atomic mass unit)
What is a mass of Beads it is a measurement but how much?
1 mass = 1200 beads
How much of what is in the objects?
Mass
Are mass and velocity forces?
No!! Force is how much work is being exerted on an object. NOT how much grav. pull (mass) or how much its accelerating (velocity)!
What is a sentence for atomic mass?
the atomic mass is how much an element weighs
