What else can I help you with?
Can you determine the identity of an unknown substance by calculating its density and observing chemical reactions?
Yes. You can divide the mass by the volume to find its density. Density is a property that can identify a substance.* * * * *No, you cannot! Density is not a property that can identify a substance unless you know that it is pure.All you can do is with mass and volume is determine the density of the substance, which could be a mixture. For example, sodium has a density of 0.97 g/cc and osmium a density of 22.6 g/cc. These two metals can be combined in various proportions to give an alloy with a density with any value between the two given numbers. I am not sure how stable such an alloy might be but the point is that you could make an alloy with the same density as tin, or iron, or lead or bronze.
The fundamental density is the ratio of the mass of a substance to its volume this is known as what?
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
Determines if an object will float or sink in a fluid?
Density. An object will float in a substance if its density is less than the density of the substance. The density of water is 1 kg /L or 1 g/ cm3. Anything with a density less than this will float.
Why do scientists use density calculations to determine the kind of substance with which they are dealing?
so that they can have a better chance of finding the mass
How can one determine the relative density of a substance?
To determine the relative density of a substance, you can divide the density of the substance by the density of water. The relative density is also known as specific gravity and helps compare the density of a substance to that of water.
How do you determine the identity of an unknown substance by observing its mass and volume?
All you can do with mass and volume is to determine the density of the substance. density = mass / volume or p=m/v after you determine the density, you can look on any density table and find the substance you are looking for. good look. -julio
How do you determine the substance given the mass?
To determine the substance given the mass, you would need to compare the mass to the known density of various substances. By dividing the mass by the volume (which can be calculated from the dimensions of the object), you can determine the density of the substance. Then, you can compare this density to known values to identify the substance.
If Using density how dowe determine if a substance is pure or not?
If a substance is not pure, the density may, or may not, change, compared to the pure substance.
How can you determine the density of a substance?
To determine the density of a substance, you would divide the mass of the substance by its volume. The formula for density is density = mass/volume. Measurements should be taken in units such as grams for mass and cubic centimeters for volume.
What does a density of a substance determine?
It determines the mass of the substance per unit volume.
How can one determine the density of a substance using the pressure and temperature values?
To determine the density of a substance using pressure and temperature values, you can use the ideal gas law equation, which is PV nRT. By rearranging this equation to solve for density ( n/V), you can calculate the density of the substance by dividing the mass of the substance by its volume.
How could density be used to determine the mass of a particular volume of a substance?
To determine the mass of a particular volume of a substance using density, you would multiply the density of the substance by the volume of the sample. The resulting value would give you the mass of the substance based on the known density and volume relationship (mass = density x volume).
How can density be used to determine the identity of a substancce?
Density can be used to determine the identity of a substance by comparing the density of the unknown substance to the known densities of different substances. Each substance has a characteristic density, so if the density of the unknown substance matches that of a known substance, it can help identify the unknown substance.
How can one determine the density of a substance using temperature and pressure?
To determine the density of a substance using temperature and pressure, one can use the ideal gas law equation, which relates the density of a gas to its temperature and pressure. By measuring the temperature and pressure of the substance, one can calculate its density using this equation.
What is the mass for 20cm3 volume?
That depends what substance you are talking about. You have to multiply the volume by the density of the substance.
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.
