How do you calculate the density of a polyurethane foam?
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
How do you calculate volume of a beaker when you have weight and mass?
To calculate the volume of a beaker using weight and mass, you first need to determine the density of the liquid it contains. Density is defined as mass divided by volume (density = mass/volume). Rearranging this formula gives you volume = mass/density. If you know the weight of the liquid (which is the force due to gravity on the mass), you can convert weight to mass by dividing by the acceleration due to gravity (approximately 9.81 m/s²) and then use the density to find the volume.
How is mass and volume determined density?
If the object has a regular shape, like a cube or sphere, its volume can be calculated readily from solid geometry. Weight divided by volume gives density. For an irregular shape, one trick for finding volume is to submerge it in a calibrated container of water. The amount of increase in the volume of the water is the volume of the object. * * * * * Mosttly correct but density = mass/volume not weight/volume. Mass is not the same as weight.
How do you know which objects are more dense or less dense?
Density is weight divided by volume. Weight is measured with a scale. Volume can be calculated if an object has a regular shape, using basic geometry, but if it has an irregular shape, it can be calculated using a graduated cylinder.
What is the volume of a 10 gram object if it weighs 8 grams under water?
The volume of the object is equal to the difference in weight when submerged in water and when in air, divided by the density of water. Using the formula: Volume = (Weight in air - Weight in water) / Density of water, we have Volume = (10g - 8g) / 1 g/cm^3 = 2 cm^3.
What is the measure of matter that is weight divided by volume?
None that I know of, but mass divided by volume is density.
Is an object's density equal to its mass divided by its length?
Not exactly. Density is weight divided by volume.
Is The weight of a substance is defined as its mass divided by its volume.?
weight is different in different gavities but mass is not, volume is not involved
How do you calculate the density of matter?
Volume occupied divided by weight
Density of solid?
Density is weight (mass actually) divided by volume.
What is the mathmatical formula for finding density?
Density is weight divided by volume.
The ------ of a substance is defined as it mass divided by its volume?
weight is different in different gavities but mass is not, volume is not involved
What is the difference between percentage by weight and volume?
They are different in non-homogeneous mixtures. Here's an example. If you put a few drops of water in a balloon, the contents are 99.9% (or so) water by weight and 99.9% (or so) air by volume.
What is weight divided by density?
Weight divided by density gives you the volume of an object. This relationship is derived from the formula ( \text{Density} = \frac{\text{Mass}}{\text{Volume}} ), which can be rearranged to find volume as ( \text{Volume} = \frac{\text{Weight}}{\text{Density}} ) when weight is expressed in terms of mass (considering gravitational acceleration). Thus, knowing an object's weight and its density allows you to calculate how much space it occupies.
Why did the Archimedes need to know to work out the density of a substance?
Weight vs volume. PLace object in container already full of water. Measure volume of liquid displaced. weight object. weight divided by volume equals density
How do you calculate the denstiy of pyrite?
Compare its weight to the weight of an equal volume of water. The weight of the specimen divided by the weight of the water equals the density of the specimen.
How do you calculate density from molecular weight?
Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.
