A blue whale has a mass of over 100 tons.

On earth, 100 kg of mass weighs 980 newtons (220.46 pounds).

If you weighed 100 lbs on Earth you would weigh 112.5 lbs on Neptune.See related for how much you would weigh on other planets.

45 kg. The same. Your mass doesn't change on which planet you're on, but your weight does.

With a sufficiently sensitive balance, the mass of a single pin can be determined. More commonly, one would weigh say 100 pins and thus know their average mass.

Every mass has gravity. If you weigh 100 pounds on Earth, then you would weigh about 16 pounds on the moon.

Gravity is expressed by the formula g = m/r2, where g is the surface gravity of an object, expressed as a multiple of the Earth's, m is its mass, expressed as a multiple of the Earth's mass (5.976·1024 kg) and r its radius, expressed as a multiple of the Earth's (mean) radius (6371 km). So for an example, Mars has a mass of 6.4185·1023 kg 0.107 Earth masses and a mean radius of 3390 km 0.532 Earth radii. The surface gravity of Mars is therefore approximately 0.107/0.532sq is about 0.38 (0.37805981118209056475775905930239) .378 x 100 lb gives 37.8lb Allow for precision in the values and the answer is anywhere between 37.6 and 37.8lbs.

Yes, the moon's gravity is about one sixth of Earth's gravity. This means that if you weigh 100 pounds on Earth, you would weigh about 16.6 pounds on the moon.

About 1/6 of what you weigh on Earth. For example, if you have a mass of 60 kg, on Earth you weight about 600 N, while on the Moon you would weight about 100 N.

If the Earth kept the same mass that it has now, but that same mass got packed into a sphere with 1/2 the present radius, then a man who weighs 100 pounds on Earth now would weigh 400 pounds on the half-sized Earth. If the outer shell of the Earth's mass were removed and discarded, leaving only the mass that's presently inside 1/2 of the Earth's radius, then a man who weighs 100 pounds on Earth now would weigh 50 pounds on the half-sized Earth. (Assuming that the Earth's mass/density is homogeneously distributed.) (This is all my opinion & I could be wrong.)

mass is how much an object weighs. If you weigh 150 pounds, then you have a mass of 150 lbs (you can say pounds if you want instead of lbs, it is just the abbreviation for pounds). if you weigh 100 kilograms, then you have a mass of 100 kg( you can say kilograms or kilo's if you want, kg is just the abbreviation).

The difference between a person's weight on the earth and on the moon has to due with the difference between mass and weight. Mass is a measure of the amount of matter and weight is the pull of gravity on that mass. Gravity on the moon is about 83% that on earth, so if you weigh 100 lbs on earth, you will weigh approximately 17 lbs on the moon.

The force of gravity on Mars is about 0.38 times that on Earth. If you weigh 100 pounds on Earth, you would weigh approximately 38 pounds on the surface of Mars.

A 100 pound person will weigh 100 pounds on Earth. This is because weight is a measure of the gravitational force acting on an object, and on Earth, this force would cause a person to weigh 100 pounds.

If you were already 100 pounds on Earth, you would still weigh 100 pounds on Earth. Your weight does not change regardless of where you are on Earth.

The question is ill-posed. Weight is mesured in Newtons (N) as it's a force, it's mass is measured in kg. There are ctually two questions mixed together here. Let's answer both: 1) If an astronaut has a mass of 100kg on earth what is his mass on the moon? 100kg - put him on a frictionless surface and try and accelerate him, it's just has hard on the moon as on earth (or anywhere else for that matter). 2) If an astronaut weighs 981N on the surface of the earth (as an astronaut of mass 100kg would) how much does he weigh on the moon? Surface gravity on the earth is 9.81m/s/s which is how we end up with the 100kg astronaut weighing 981N. On the moon surface gravity is only 1.62m/s/s so the same astronaut would weigh 162N - about 1 sixth that on earth.
