Density is independent of the amount of material in a sample. A sample of a homogeneous substance used to find the density can have any volume. If a cm3 of the substance weighs 8.1 grams, then 10 cm3 will weigh 81.0 grams.
We might consider water in a glass or bottle as an example. A small sample will have a given weight (mass) because water has a given density. Ten times that sample volume will have ten times the mass of that volume of water. The density of water does not change if we examine water in a small glass and another sample of the same water in a gallon jug.
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
yes because the quota sample include the random sample and when we have over estimation we will use the quota sample
larger is the wrong word to use here as it would depend on density, kg is a unit of weight not size. 1kg is certainly greater than 1g assuming the two substances are the same. but it is wrong to use the word larger in this question.
8.57 g D=mass/volume Wanting to fight weight of the vial so you would use Mass=density*volume 8.6mL is volume .997g/mL is density
None - if you cycle! It will depend on the fuel efficiency of your vehicle, your driving style, the traffic, how much you use the electrical equipment (eg air con), how much weight you are carrying/pulling.
density = mass / volume
To find the density of gold, you would need to divide the mass of the gold sample by its volume. The density of gold is typically around 19.3 grams per cubic centimeter. So, if you have the mass and volume of the gold sample, you can use this information to calculate its density.
To find the density of water at a specific temperature, you can use a reference table or formula that provides the density of water at different temperatures. Alternatively, you can measure the mass and volume of a sample of water at that temperature and use the formula density mass/volume to calculate the density.
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.
The density of a small solid sample can be determined by using the displacement method. This involves submerging the sample in a known volume of liquid (such as water) and measuring the volume of liquid displaced. The density is then calculated by dividing the mass of the sample by the volume of liquid displaced.
One common method to test the density of wood is to measure the mass and dimensions of the wood sample, then calculate its volume. By dividing the mass of the wood sample by its volume, you can determine the density of the wood in grams per cubic centimeter. Another method is to use a densitometer, a device specifically designed to measure the density of materials like wood.
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
To find the volume of mercury, you need to know the density and the mass of the sample. Once you have the mass, you can use the formula: volume = mass/density to calculate the volume of mercury.
To calculate the amount of ice water needed to cool the sample to 20 degrees Celsius, you would need the initial temperature of the sample, the mass of the sample, and the specific heat capacities of water and ice. With this information, you could use the equation q = m * c * ΔT to determine the quantity of ice water needed to cool the sample.
Early prospectors used density to determine whether they had found gold or pyrite by comparing the weight of the mineral sample to its volume. Gold has a higher density than pyrite, so a sample of gold would feel heavier for its size compared to a sample of pyrite. By calculating the density of the sample using the formula density = mass/volume, prospectors could determine if they had found gold or pyrite based on the density value obtained.
To calculate the mass of the sample using dimensional analysis, you would use the expression: mass = volume × density Substitute the given values for volume (10.0 mL) and density (7.87 g/mL) into the expression to calculate the mass of the iron sample.
