[object Object]
To find the density of an irregular object, you would first measure its mass using a scale. Next, you would find the volume of the object using displacement method or by calculating it with water displacement. Divide the mass by the volume to calculate the density of the irregular object.
To find the density of an irregular object, you would need to measure its mass using a scale, and then calculate its volume using a displacement method or by measuring dimensions and using a formula. Once you have both values, divide the mass by the volume to determine the density of the irregular object.
To obtain the density you need to know the mass, and the volume of the object.So you'd have to weigh it using a balance to obtain the mass.The easiest way to measure the volume (particularly if it's an irregular shape) would be via the displacement of water.density = mass / volume
To find the density of an irregular shape, you would first measure its mass using a scale. Then, you would need to measure its volume using a displacement method or by using water displacement. Once you have both the mass and volume, you can calculate density by dividing the mass by the volume.
Without knowing the density of an object, it's not possible to calculate it's volume by weight. A 1kg piece of granite and a 1kg piece of igneous rock would be very different in volume.
Weigh the piece of maple (you've indicated it is about 10 grams) Completely submerge it in a liquid and measure the volume of liquid displaced Density = mass/(volume displaced) or about 10g/(volume displaced)
by submerging it into a glass of water that has measurement lines and taking the difference between the original amount of water and the water with the object in it.You would use water displacement to find the volume of an irregular object.
To calculate the volume of a piece of gold, you need to know its density. Gold has a density of around 19.32 g/cm^3. Using this density value, you can calculate the volume by dividing the mass (2 g) by the density. The volume of 2 g of gold would be approximately 0.104 cm^3.
If you can somehow describe the shape, a popular tool is integration. This means that you imagine cutting the object into thin slices, calculate the volume of each slice, then add everything up.(And if the slices have an irregular shape, they, in turn, are cut into thin strips - so you would be using a double integral.)
To calculate the density of an irregular shaped object like a key, you would first measure its mass using a scale. Next, you would measure its volume using a displacement method with water. Finally, you would divide the mass of the key by its volume to determine the density.
The volumes of small irregular solids are usually easily measured by measuring the volume of fluid displaced when they are immersed in a liquid. For example: You would have to put the object in a measuring glass with water in it. (~1/3 filled) Put the object in it and then get the number from the measuring glass (beaker etc. mostly beaker) and that is how you measure a irregular solid!
By definition, an irregular object is one that does not have an easy mathematical representation, it is extremely difficult (if not impossible) to calculate its volume without placing it into a solution of some sort. Attempts to calculate volume otherwise would be subject to severe rounding error, and would thus make it unsuitable for scientific use. For the very special case where the object is uniform and/or its density, ρ=m/V, is known, then its volume could be determined from its mass, V=m/ρ.
