When equal masses and volume of two substances are mixed find the density of each substance?
Take two hypothetically substances A and B
in equal masses (eg. 1 kg A and 1 kg B) and taken in equal volumes ( 0.8 L A, and 0.8 L B), then they already have the same density (both are 1.25 kg/L A and 1.25 kg/L B) each other apart. (that's how the question was formulated)
HOWEVER:
when mixed together the masses add up (Mass conservation law) to 2 kg A+B,
BUT total volume is not exactly added up (no conservation law for volume). Normally some contraction takes place, then Vtotal < 1.6 L (sometimes more than 2% contraction)

What is the difference of relative density and density?
Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of a reference substance (usually water). Relative density is dimensionless and is often used to identify substances or determine their purity based on their comparison to a standard substance.
Equal volumes always mean equal 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.
What factors determine density?
The factors that determine density include the mass and volume of a substance. Density is calculated by dividing the mass of an object by its volume. Different substances have different densities based on how closely packed their molecules are. Temperature and pressure can also affect the density of a substance.
Which conclusion is supported by the given data in the table mass volume and density measurement of substances?
The conclusion supported by the data in the table depends on the actual values provided. If the density remains constant for all substances, you can conclude that density is consistent. If the density changes with mass and volume, you can infer a relationship between mass, volume, and density.

When you compare masses of the same volume of different substances you are doing what?
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.
Is density the volume of equal masses of substances?
yes
What has a greater density 0.8 or 0.7?
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.
What is the ratio mass of a substance to the volume of the substances?
Its density.
What is the ratio of the mass of a substance to the volume of the substances?
That's the definition of the density of the substance.
What is the relationship between the molar mass and density of a substance?
The relationship between the molar mass and density of a substance is that the molar mass affects the density of a substance. Generally, substances with higher molar masses tend to have higher densities. This is because the molar mass represents the mass of one mole of a substance, and denser substances have more mass packed into a given volume.
The amount of mass in a given volume of a substance is the substances?
That is called "density".
What is the difference of relative density and density?

Equal volumes always mean equal 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.
What substances consist of density?
No substance 'consists' of density. Rather density is a property of matter or substance. It is the amount of matter of a substance in a certain volume of that substance. A combination of a unit of mass (eg. kilogram) and a volume (eg. a cubic metre) You would say that a substance has a density of so many kilograms in a cubic metre.
What is how tightly packed a substances molecules are?
what is the measure if how tightly matter is packed into a givin volume of a substance
