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.
How gram is equal to 1 spoon?
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.
What laboratory apparatus is used to measure masses of substance or objects?
A balance.See the Related Questions to the left for more information.
In 16 kilograms how many in liters?
Different substances have different densities. If you're talking about water, then 1 liter masses 1 kilogram, so 16 liters.
How does e equals mc2 relate to fission or fussion?
When a single heavy nucleus splits into two or more lighter nuclei (fission), the sum of their masses is less than the mass of the original nucleus. Some mass is missing, and some energy is released. When two light nuclei fuse into a single heavier nucleus (fusion), the mass of the heavier one is less than the sum of the masses of the two light ones. Some mass is missing, and some energy is released. In both events, the missing mass has been converted to energy. If the amount of missing mass is 'm', and you multiply 'm' by the square of the speed of light 'c2' , the answer you get is the amount of energy that was released 'e'. e = mc2
What has a greater density 0.8 or 0.7?

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.
Can the mole ratio from a balanced chemical equation be interpreted as a ratio of masses?
No, the mole ratio from a balanced chemical equation cannot be directly interpreted as a ratio of masses. The mole ratio represents the ratio of moles of one substance to another in a chemical reaction, whereas the ratio of masses would depend on the molar masses of the substances involved. However, if you know the molar masses of the substances, you can convert between moles and masses using this information.
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.
When equal amounts of energy are transferred to or from equal masses of different substance the substance will undergo different changes in temperature because of their different?
specific heat capacities. The substance with the lower specific heat capacity will experience a greater change in temperature compared to the substance with a higher specific heat capacity.
What is the effect of different masses on the same substances on the melting point?
The question isn't worded very well, so I'm not sure this is the answer to what you were trying to ask. The bulk mass of a substance has no impact whatsoever on the melting point of that substance. Covalently bonded molecules with higher molecular masses tend to have higher melting points, if the substances are roughly the "same kind of substance", which is an ill-defined term so you shouldn't put too much faith in this until you've studied chemistry enough to have developed a sort of intuition about what it means.
Is density the volume of equal masses of substances?
yes

When equal masses and volume of two substances are mixed find the density of each substance?
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.
Substances that are the same chemical element but have different masses are called?
isotopes
How many micrograms is ppm?
This question cannot be answered. ppm is a ratio: so many parts of one substance per million parts of another. That can only be converted into mcg if the relative masses of the two substances are known.
