Kilograms.
You find a measure of the amount of matter in the rock.
You put it on a scale or a triple-beam balance. It'll give you the mass. However, if you have the density of the rock, divide it by the volume to find the mass mathematically. You can also find the volume by the water displacement method, where you placed the rock in a graduated cylinder/beaker filled partially with water and record the difference between the original water level and the raised water level after placing the rock inside the container.
density = mass divided by volume = 100/25 = 4 grammes per cubic centimetre.
It depends on the size and mass of the rock. For a "normal" rock (as opposed to merely a stone) I suggest a crane with some means for measuring the rock's mass. A number of pulleys, each with a weighing machine should do the trick. Alternatively, you could use a weighbridge, if there is one in the vicinity. To obtain its volume, you probably need a 3-d laser-profiling device. That should give the most precise measurement of its volume.

Weigh it! The mass is usually found indirectly, via the weight.
The mass of the rock is 350 grams. The measurement on a pan balance represents the mass of the rock, which is the amount of matter it contains.
You can use a balance or scale to find the mass of a rock. Place the rock on the balance or scale and record the reading to determine its mass.
Place a specific amount of water in your bottle. Record the volume. Place the rock in the bottle. Read and record the new volume of water. Subtract the first volume measurement from the measurement after you added the rock. The difference is the volume of the rock.
Yes. Kilogram is the unit of mass.
To calculate the mass of the rock, you would need to know the acceleration due to gravity acting on it. Using the formula Force = mass * acceleration, you can rearrange it to find mass. Without the value of acceleration, we cannot determine the mass.
To find out how many small rocks are needed to equal the mass of the larger rock, we first convert the mass of the larger rock from kilograms to grams: 3 kilograms = 3000 grams. Since each small rock weighs 2 grams, to find the number of small rocks needed, we divide the mass of the larger rock by the weight of each small rock: 3000 grams / 2 grams per small rock = 1500 small rocks. Therefore, it would take 1500 small rocks to equal the mass of the larger rock weighing 3 kilograms.
You find a measure of the amount of matter in the rock.
A rock with a volume of 4mL would have a greater mass than a rock with a volume of 1mL. Mass is directly proportional to volume, so as volume increases, mass also increases assuming the density of the rocks is constant.
The answer will depend on how big the rock is.
