The density of a piece of granite with a volume of 340 cm and mass of 918 g would be 1,400 grams. This is a math problem.
Multiply them: density*volume = mass
First you weigh it, then you put it in a beaker with a known amount ow water in it. By noting how much the volume of water increases you get the volume of the magnetite. Now you got all you need to determine the density.
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
you get volume by dividing mass by density or by achimedes/relative density method
calculate density of sponge ?
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
You times the length by the width by the height to find volume. To find the density do mass divided by volume.
The density of the piece of lead is 10.89 g/mL. This is calculated by dividing the mass (49.01g) by the volume (4.5mL).
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
The equation to find the density of a material is density = mass/volume. To find the density of glass, you would need to measure the mass of a sample of glass and divide it by the volume of the sample. The density of glass can vary depending on the type of glass.
The density of the piece of paper is calculated by dividing its mass (15.5 g) by its volume (27.0 cm3). Density = mass/volume = 15.5 g / 27.0 cm3 = 0.574 g/cm3.
Volume = Mass/Density
Find its volume. Divide the mass by the volume to get the density.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
To find the volume of the alloy, use the formula for density: Density = Mass / Volume. First, calculate the volume of water displaced by the alloy when immersed: Volume of water displaced = Mass in air - Mass in water. Then, use the density of water (1g/cm^3) to find the volume, as the volume of water displaced equals the volume of the alloy. Finally, calculate the density of the alloy by dividing its mass by the volume obtained.
To find density with just the volume, you need to know the mass of the object as well. Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = Mass / Volume.
To find the density of a piece of coal, you would first measure the mass of the coal using a scale. Next, you would measure the volume of the coal using displacement method or a caliper. Finally, divide the mass of the coal by its volume to calculate the density, which is typically expressed in g/cm³ or kg/m³.
