The desity of a compound is a specific chemical property that can be looked up in reference materials. The desity of sucrose is 1.587 g/cm cubed and the desity of glucose is 1.54 g/cm cubed.
The answer depends on what the numbers measure. If they are the masses of equal volumes of substances, then the substance with mass 0.8 is denser. On the other hand, if the numbers refer to the volumes of equal masses of two substances, then the substance with volume 0.7 is denser.
A graph about masses and volumes would represent density.
Resistance to deformation.
A spoon is a measure of volume. Different substances have different densities so that the same volume of two substances can have very different masses.
The result of mixing equal MASSES of water at different temperatures will be the mean of the two temperatures. Unless you are being very sophisticated and are taking the thermal expansion into account, the same will apply to volumes.

No, not unless they are made of the same substance. Different substances have different densities, which means that the same volumes will have different masses.
yes
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
If two solids have the same masses but different volumes they have different densities.

The masses are equal.The volumes are different.The values are different.
