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.

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.
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.

Not necessarily. Equal volumes do not always mean equal masses because different substances have different densities. Denser substances will have more mass in a given volume compared to less dense substances.

If equal masses and volumes of two substances are mixed, the density of the resulting mixture will be the average of the densities of the two substances. To find the density of each substance separately, you would need additional information such as their masses and volumes before mixing.
You are comparing their densities. Density is a measure of how much mass is present in a given volume. By comparing the masses of the same volume of different substances, you can determine which substance is more or less dense than the others.
yes
Yes, using the balanced chemical equation for the reaction, you can determine the molar masses of the products by calculating the sum of the molar masses of the atoms present in the products. The stoichiometry of the reaction will determine the ratios in which the reactants react to form products.
different equal
Yes, two different substances with the same volume can have similar masses if their densities are similar. Density is the amount of mass per unit volume, so substances with similar densities will have similar masses for a given volume.
You can determine which medium is denser by comparing their densities - the medium with the higher density is denser. This can be done by measuring their masses and volumes, or by observing which one displaces more fluid in a graduated cylinder when placed in it.
Not necessarily. Mass is a measure of the amount of matter in an object, so two objects of the same size and shape can have different masses if they are made of different materials or have different densities.
The masses are equal.The volumes are different.The values are different.
