A sample of xenon gas occupying 10.0ml is collected in laboratory at 27 C and 1.25atmosphere.what is the volume at standard condiions?
It will occupy 11.8 ml.
What property like volume depends of the size of the sample?
The volume and the mass of sample both depend on the size of the sample.A small sample has small volume and small mass, a big sample has big volumeand big mass. But the ratio of mass to volume is constant for a pure sample ofa substance, no matter what size the sample is. That ratio is called the densityof the substance.
What is the use of pipette in the laboratory?
A pipette is a laboratory tool used to transport a measured volume of liquid.
How could determine the concentration of ascorbic acid in an unknown sample?
The concentration of ascorbic acid in an unknown sample can be obtain by conducting a few steps by using the DCPIP test. Firstly, we must obtain the volume (dm ) of the sample solution which are required to turn the DCPIP solution (blue) colour into colourless. After obtaining the volume we use an electronic balance to obtain the mass of the sample solution in gram (g). Then we use the concentration formula of [mass (g) of solute per volume (dm ) of solution] to find out the concentration. Hence. The concentration obtained was the concentration of ascorbic acid.
In the laboratory volumes of liquid are usually measured with an?
A graduated cylinder is used to measure the volume of liquid in a laboratory.
What volume of iron would be needed to balance 129.96 gm of lead on a two pan laboratory balance?
Interesting question. the density of lead is 11.34 grams per milliliter. Density = grams/milliliters so, 11.34g/ml = 129.96g/ml 11.34(ml) = 129.96 ml = 11.46 milliliters so at least that many milliliter volume of iron to balance the lead.

What are the laboratory apparatus that use to measure mass and volume?
For measuring the mass (solids) of a substance you would need to use a balance. Measuring volume (liquids) a volumetric flask is required.
What is a graduated cylinder and a balance?
A graduated cylinder is a glass or plastic device used in laboratory to measure volume of liquids.
What tools do use to determine the volume and mass of a rock?
A measuring jug is all you need for the volume and a mass balance is needed to determine mass.
What measurement must you make to find density of a sample of matter?
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.

What can you use to help evaluate the density of a mystery liquid?
you measure the mass ( weight ) of the object and divide it by the object's volume
The volume of a sample of water is 20cm3 the mass of?
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
Which tools measure length volume and mass and their units?
-- Length is measured by rulers; they are often wood. -- Volume is measured by measuring cups; they are usually glass. -- Mass is most often measured by a laboratory balance; they are metal.
How do you determine the concentration of ascorbic acid in unknown sample?
first measure the volume of the sample solution needed to change the blue color of the DCPIP solution into colourless. then, weigh the mass of the sample solution. finally calculate the concentration by using the formula: volume required t change the color of DCPIP solution (dm) per mass of the sample solution (g)
Distinguish between relative density and density?
There is difference between relative density and density.Density: it is the ratio of total weight of given sample to the total volume of that given sample, for example soil.Relative density: it is the ratio of the two densities,field density to the laboratory density. this is particularly useful and is used in the fields as it is not possible to attain 100% density which we determine in the laboratory tests, as the laboratory tests are conducted in controlled environment and we can not do that in case of field because of vastness. also field density is less then the laboratory density.
