Is it true that the weight of a substance is defined as its mass divided by its volume?
This is false. For most practical purposes, ie 'on planet Earth,' the terms 'mass' and 'weight' mean the same thing. Off-planet, mass just equals mass, as weight is a function of gravity.
Why are mass and weight used synonymously on earth?
Because on a bathroom scale, you often measure your 'weight' by pounds or kilograms. But really, it should be measured in newtons. Pounds and kilograms are used for mass. So you are really measuring your mass on a scale, not your weight.
If you weight 300 Newtons on earth then what is your mass and weight in mars?
You need to:1) Divide the weight by Earth's gravity, to get the mass. 2) Remember that the mass will be the same on Mars. 3) Multiply the mass by the gravity of Mars, to get the weight on Mars.
What is different about weight and mass measurement?
The difference between weight, OK say that your on the moon your weight is the same that it was on earth but your mass will be totally different then it was on earth.
What is your weight on earth if your weight on the moon is 36kg?
There is gravity on the moon! The gravity on the Moon is 1/6th that of what is observed on Earth. An object with a weight of 36 kg on Earth would weigh 1/6th that on the Moon. 1/6th of 36kg is, 6 kg. An object with a MASS of 36 kg on Earth would have the same 36 kg MASS on the moon. Mass is the amount of matter that makes up an object, whereas WEIGHT is the measurement of the force of gravity on that MASS. This is why your weight will change when visiting other planets, but your mass stays constant plant to planet!

What is the mass of Mars in terms of Earth's mass?
The mass of mars is about 0.107 Earth masses.
What is the mass of 64.44 grams?
The mass is 64.44 grams. But the difference between mass and weight is that mass is weight is how heavy it is on the planet you weigh it on and mass it the weight it is on Earth, whether is is on Earth, or not.
Is the weight of the earth equal to 110 billion people?
No, the weight of the earth is much greater than that of 110 billion people. The mass of Earth is about 8.6*10^22 times the mass of the average human. In other terms about 86 sextillion or 86 thousand billion billion times the mass of the average human.
Why will a person's mass never change whether they are on earth or on the moon?
Because mass is not the same as weight. Weight is mass times gravity so your weight will change if you are on the earth or moon but your mass will stay the same.

How the weight and the mass will change if a planet has gravity half as strong as Earth?
Mass remains the same; weight will be one half that of the same mass on earth.
What is different about weight and mass measurement?
The difference between weight, OK say that your on the moon your weight is the same that it was on earth but your mass will be totally different then it was on earth.
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
How much does the earth weigh not based on gravitational attraction?
This may be a trick question. We often use the terms "weight" and "mass" interchangeably, but we use the term "weight" to refer to mass that is in a gravitational field (and generally the gravitational field of earth). . If a person weighs 150 pounds, it means that we have used "pound" as a reference, and that involves (or invokes) the effect of the pull of the earth on that person. But that person has mass that is independent of gravitational attraction. A person who has a mass of 150 pounds has that mass no matter where he may be. That person is weightless in deep space where there isn't anything of substance around to exert a gravimetric pull on the person. Mass is present, but there is no weight. . The earth is not said to have weight. Instead, it has mass, and that mass is a bit short of 1024 kilograms. . See an answer to a related question, "What is the weight of earth?"
Why is there a difference in an object's weight on Earth and on the Moon?
Because the gravitational force between any two objects depends on the product of both their masses. The object's weight on earth depends on the object's mass and the earth's mass, whereas its weight on the moon depends on the object's mass and the moon's mass. Since the moon's mass is very different from the earth's mass, the object's weight is also different there.
