If you look up "Mars" on the Wikipedia (or some other source), and specifically look for "Surface gravity", you will see that it is 3.711 meter / second squared. This is equivalent to 3.711 newton / kilogram. That is, each kilogram has a weight of 3.711 newton.
Mars is the second smallest planet in the solar system. It has a mass of .107 and a density of 3.93 g/cm.
6 kg of mass weighs 58.8 newtons (13.23 pounds) on the surface of Earth,
and 22.3 newtons (5.02 pounds) on the surface of Mars.
22.33N. A 6kg object would have a weight of 58.84N when it is on earth
but a weight of only 22.33N on the surface of mars. So times 2.6.
A 100-kg mass would weigh about 83.4 pounds on Mars, vs. 220.4 pounds on earth.
6.4185 × 1023 kg
6.4185×10^23 kilograms.
200kg here is 75.4kg on Mars.
514kg - 635kg
If you weighed 78 pounds on earth, you would weigh 29.4 pounds on mars.
On Mars, you'd weigh 34.2 pounds.
On Mars, you'd weigh 41.04 pounds.
On Mars you weigh 30% of what you do on Earth. For example, if you weigh 122lbs on Earth, you would only weigh 46lbs on Mars.
27kg is 10.179kg on Mars.
175.4 kilograms
That depends on where you weigh 142 pounds.-- If you weigh 142 pounds on Earth, then your mass is 64.4 kilograms. (rounded)-- If you weigh 142 pounds on the Moon, then your mass is 389.2 kilograms. (rounded)-- If you weigh 142 pounds on Mars, then your mass is 169 kilograms. (rounded)-- If you weigh 142 pounds on Jupiter, then your mass is 24.4 kilograms. (rounded)...etc.

514kg - 635kg
On average, great white sharks normally weigh about 2240-2268 kilograms
You are weightless on mars because there is zero (or no) gravity.
