What is the density of an unkown substance that has a volume of 23.0 ml and a mas of 47.5g?
Density is mass/volume.Density of the unknown substance = 47.5g/23.0mL = 2.07g/mLHint: Mass is always measured in grams of some sort; mg, g, kg, etc... Volume is measured in mL, L, m3, cm3, etc...
What are the usefulness of density in identification of unknown substance?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What is the percent of the mystery substance?
I'm unable to calculate the percentage of an unknown substance without more information about its composition or quantity.
What is the density of an 84.7 g sample of an unknown substance if the sample occupies 49.6 cm3?
Density is calculated by dividing the mass of a substance by its volume. In this case, the density of the unknown substance can be calculated by dividing the mass of 84.7 g by the volume of 49.6 cm3. Therefore, the density of the unknown substance is 1.71 g/cm3.
What are two ways to compare the density of a unknown substance?
One way is using the formula D=m/v. Or you could get some water and put the substance inside the water and see if the density is lower or higher.
What procedures would you follow if you wanted to calculate the density of an unknown substance?
To calculate the density of an unknown substance, first measure its mass using a balance. Then, determine its volume by either measuring its dimensions and calculating the volume or using displacement method in a liquid. Finally, divide the mass by the volume to calculate the density of the unknown substance.
Why is it not necessary to know the volume of a substance when calculating its density?
If you want to CALCULATE the density of an unknown substance, you need to divide its mass by its volume, so you need to measure both first. If it is a homogeneous (uniform) substance, and you can take away a piece, you can take any sample. Any piece of the substance will have the same density.
An 8.192-mL sample of an unknown has a mass of 9.02gWhat is the density of the unknown?
Density is equal to mass divided by volume. In this case, the mass is 9.02g and the volume is 8.192mL. Calculate the density by dividing the mass by the volume: 9.02g / 8.192mL = 1.10 g/mL. So, the density of the unknown substance is 1.10 g/mL.
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 density be used to identify an unknown substance?
Finding the volume and comparing it to the mass will give you the density, then it is simply a matter of looking up which materials have that density to find what it is. And that is how you can tell howthe density can be used
What is the density of an unkown substance that has a volume of 23.0 ml and a mas of 47.5g?
Density is mass/volume.Density of the unknown substance = 47.5g/23.0mL = 2.07g/mLHint: Mass is always measured in grams of some sort; mg, g, kg, etc... Volume is measured in mL, L, m3, cm3, etc...
What is the density of a rock that has a mass of 56 grams?
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
How do you find the density of an unknown mineral?
To find the density of an unknown mineral, you can measure its mass using a scale and then measure its volume by displacement in water. Divide the mass by the volume to calculate the density of the mineral.
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
What are the usefulness of density in identification of unknown substance?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What is the density of a 26.5mL sample of an unknown substance that has a mass of 43.54g?
density = mass/volume = 43.54g / 26.5ml ≈ 1.643 g/ml
A 30ml sample of an unknown liquid has a mass off 100g what is the density?
Density is calculated by dividing the mass of a substance by its volume. In this case, the density of the unknown liquid is 100 g / 30 ml = 3.33 g/ml.
