What substance can be calculated by dividing its mass by its volume?
It's not exactly a "substance" but Density = Mass / Volume
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.
Is the density of a substance obtained by dividing its volume with its weight?
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
Density has the ratio of what to what?
Density is the ratio of the mass of a substance to the volume of the substance.
How do you find steel density formula?
You can look up the density of different materials in a table of densities. But if you want a formula, just use the definition of density as mass / volume. This is also how you would measure the density of a substance of unknown density.
What substance can be calculated by dividing its mass by its volume?
It's not exactly a "substance" but Density = Mass / Volume
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.
What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
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 is the density of an unkown substance that has a volume of 23.0 ml and a mas of 47.5g?
The density of the unknown substance is calculated using the formula: Density = Mass / Volume. Plugging in the values given: Density = 47.5g / 23.0ml = 2.07 g/ml. Therefore, the density of the unknown substance is 2.07 g/ml.
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.
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
What is the density of an unknown substance with a mass of 16.5 g and a volume of 2.2 cm3?
Density = Mass/Volume = 16.5 g / 2.2 cm3 = 7.5 g/cm3
When you divide the mass of a substance by its volume you get its what?
You get its density. Density is a measure of how much mass is contained within a specific volume of a 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.
How do you calculate the density of a substance?
The density of a substance is calculated by dividing its mass by its volume. The formula for density is: Density = Mass / Volume. This calculation gives you a measure of how tightly packed the molecules are in a given sample of the substance.
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.
