10,000 rpm for 8 min is good for anthrone method to estimate total sugars in the sample
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
That depends on the particular sample of DNA.
350 g sample of CO contain 12,49 moles.
That would probably be polymerase chain reaction or PCR for short.
Why is it that dried food sample can contain lower numbers of microorganisms
Sampling is a method of selecting experimental units from a population so that we can make decision about the population. Sampling design is a design, or a working plan, that specifies the population frame,sample size, sample selection, and estimation method in detail. Objective of the sampling design is to know the characteristic of the population.
simple random sampling method

One way of testing is send a sample of the area thought to be contaminated to a lab. The lab should be able to run a polarized light microscopy test.
In external standard method we run a standard for the substance we are looking for in our sample and than run our sample in the same conditions. we will obtain peaks for the sample and standards and can correlate the sample with the standards and can determine the concentration of the same in our sample. for more details contact vani2007
Western blot is used to detect any specific protein found in a sample. Normally tissue or cell lysates contain tons of different kind of proteins. By doing this analytical method one can identify the specific protein from the crude sample by antibodies.
The sample must contain Uranium-235.
The sample must contain radioactive elements.
A random sample is a subset of individuals or items selected from a larger population in a way that each member of the population has an equal chance of being chosen. This method helps to ensure that the sample is representative of the overall population, allowing for generalization of results.
Pour plate method
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.
