Ceratinly. It depends on their densities.
Yes, because mass = volume x density.
YES!!
Take three identical bottles. Fill one with air, one with water, and one with stones. The volumes of all three bottles are the same, but their weights are different, because they contain different masses. Different substances can easily have different masses in the same volume. That's why the concept of "density" is so useful.
the volume could be different that could lead to the same density. For example: d=m/v so you would have a mass of 10 for compound A and a mass of 5 for compound B, and the volume of compound A is 2 and the volume of compound B has a volume of 1. Therefore both densities equal 5.
Density is the relationship between mass and volume. the number of molecules in a given mass is molarity. -------------------------------------------------- No it is not. Because atoms come with different masses, so you could have 1 billion atoms of hydrogen occupying the same volume as 1 billion atoms of gold but the gold would weigh more than the hydrogen.
could may also from when air masses of different temperatures collide.
Your question is very nearly meaningless, because "in space" is not a well defined location and different locations and motions in space would have different properties. In freefall, which is what I suspect you meant, objects have no "weight" per se, but they still have inertia. It would therefore be possible to move objects you could not move on Earth, but it would not necessarily be easy, and if the object was already moving it could be difficult to stop it.
Sure. Kinetic energy depends on both mass and speed. So two objects could have different speeds, but if their masses are also different by just the right amount, their KE's could be equal.
Yes, that is possible.
Definitely. Let's be a little unscientific for a moment. Let's say you had a 1 cup measure(volume). If you fill the cup with cotton the mass would be different from a cup filled with lead.The difference is the density of the substances in question

No. Density is a ratio; it is mass divided by volume. Anything that you can weigh has a non-zero density, but the weight of the thing is related to its mass and the gravity where it is being measured. You could have two objects of vastly different density, but the weight of the objects could be the same.
Identical objects should have the same volume. Unless they only look identical but are made of different material or made up of some other compound that could cause it to have a different volume. For example, two small Starbucks cups would hold the same amount of water. The only time it wouldn't is if there are ice cubes, or something else in the cup that takes up space.
You will get the maximum volume in the case of a sphere. You can use the formula for the surface of a sphere to calculate the radius; from there, you can calculate the corresponding volume.Similarly, for other objects, such as a cube, the volume you get will be less.
Compare their weights on scale's have to select scales depending on the size of the objects to find a objects density divide the objects mass by its volume.
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them
There are many different ways you could divide 105 objects or people into groups. You could have one group of 105, or 2 groups of 52 and a half objects for example.
