A cm (centimetre) is a measure of distance, not volume. As a result, there can be no matter inside 1 cm of the mineral.
Yes. That's what specific gravity is all about - the comparison of the density of a material to that of an equal volume of water. If a material or substance has a specific gravity equal to that of water, its specific gravity (sometimes called "spee gee" by the chemists) is 1. If it is more dense, say twice as dense as water, its spee gee will be 2. If the spee gee of a substance, in this case a mineral, is less than 1, it is less dense than water and will float. There may be a few exceptions for porous materials, but this is the rule.

The cost of the higher specific gravity puree is higher because it is more concentrated due to a lower percentage of water. More tomatoes are used to make the same volume of puree if the specific gravity is higher. The specific gravity is a means of assessing how concentrated the puree is. More water is liberated from the tomato puree to make it more concentrated. More tomatoes are used, hence the higher cost.
A milliliter of water, by definition, weighs one milligram. That is its mass. When 150 mL of water freezes, the volume of the water will change, but the mass will remain the same. So 150 mL of water will weight 150 mg, no matter what state of matter it's in.
one liter is always one liter it doesn't matter if it is in a water bottle or or a bucket
Specific gravity is a comparison of the density of one material to the density of water (at 4 degrees C). When a mineral has a specific gravity (SG) of 7.0 it means that the mineral is 7.0 times as heavy as the same volume of water.
specific gravity = relative density ( relative to water) , so if the mineral is 10 times the density of water, then its specific gravity is 10
it would be the same specific density in the beginning, 5.5
Water
There's 5.5 times more mass. Specific gravity is the density of a material in relation to the density of water, so the 5.5 gives the answer.
A specific gravity of 4.0 for a mineral means that a given volume of the mineral has 4.0 times the mass of the same volume of water.

Specific gravity
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
it is important because it helps determine what the mineral you are looking for is
