The gravity on Mars is .376 that of Earth's. Therefore, you'd weigh 18.8Kg.
If you had a 50kg weight on Earth, it would weigh ~zero on the space station. It would still have a mass of 50kg--meaning it would difficult to move, and hurt very bad if it wumped you on the head, but placed on a scale, it would show 0. Likewise, if you had that 50kg weight and a scale on an elevator here on Earth, the scale would read 50kg. Say at the top of a 100 floor building, the elevator's cable and safety devices broke and the elevator, you, the 50kg weight and the scale were all in free fall. For a very short time, the 50kg weight would weigh zero. You would weigh zero. The scale would weigh zero. Until the elevator hit the ground.
50kg here is 18.85kg on Mars.
The weight of 50kg of gold is 50kg. Gold is typically measured in weight units such as kilograms or grams. So, 50kg of gold would weigh 50kg.
If your mass is 50 kg, then you weigh about 18 pounds on the moon, about 39.6 pounds on Mars, about 110 pounds on earth, and exactly zero while you're coasting through space at constant speed on your way from one of them to another. Your 50kg doesn't change. That's your 'mass', not your weight.
There would be 100 oranges in a sack weighing 50kg. This calculation is based on the fact that three oranges weigh 500g, which is equivalent to 0.5kg. Therefore, 50kg divided by 0.5kg is equal to 100 oranges.
50kg
About 10% less than you do on Earth.
Your mass would still be 50kg on the moon because mass is a measure of the amount of matter in an object, which does not change with location. However, your weight would be different on the moon due to the weaker gravitational pull compared to Earth.
120lbs or 50kg.
50kg
Your mass remains the same, which is 50 kg, regardless of the celestial body you are on. Weight is a measure of the force of gravity acting on your mass, so your weight on the moon would be about 1/6th of your weight on Earth due to the moon's weaker gravity.
The weight of an object is the force of gravity acting on it. On Earth, the weight of a 50kg astronaut would be approximately 490N (using the formula weight = mass x gravity, where gravity on Earth is 9.8 m/s^2).
