How can you calculate Gallic acid equivalents for total phenolic constituents?
The total phenolic content can be calculated as gallic acid equivalent (GAE) by the following equation: T=CxV/M. T is the total phenolic content in mg·g-1 of the extracts as GAE, C is the concentration of gallic acid established from the calibration curve in mg·ml-1, V is the volume of the extract solution in ml and M is the weight of the extract in g.
Which two samples of gas at STP contain the same total number of molecules?
Theoretically, if they have the same volume, all samples will contain the same number of molecules.
How do they know how much coal is in a coal mine?
They core drill from the surface down and remove samples. These core samples give them the coal seam thickness and coal quality. Multiply the seam thickness by total area and you have the coal reserves, typically measured in acre-feet.
How do you prepare neural ferric chloride solution?
The ferric chloride test is used to determine the presence or absence of phenols in a given sample. Enols give positive results as well. The bromine test is useful to confirm the result, although modern spectroscopic techniques (e.g. NMR and IR spectroscopy) are far superior in determining the identity of the unknown. The quantity of total phenols may be spectroscopically determined by the Folin-Ciocalteau assay.
Is ethanol primary or secondary alcohol?
In order to be a secondary alcohol, the carbon with the alcohol moiety must be bonded to two other carbons. There are only two carbons total in ethanol, so it cannot possibly be a secondary alcohol. The smallest/lowest molecular weight secondary alcohol is cyclopropanol, which has three carbons: one for the alcohol group, and two others for it to be bonded to.
What is protein assay?
Protein assay is the determination of concentration or total level of protein in a solution.There are various protein assays employed like bradford assay and lowry assay

What does Assay of psa total 84153-GA mean on a lab bill?
"Assay of PSA total 84153-GA" means the patient had a PSA (prostate specific antigen) test done. This is a common screening test in men in middle age and older. 84153 is the CPT code for the test.
Test samples at 0.17 gram 0.204 gram and 2.3 grams What is the total weight of the three samples?
2.674 g
A chemist weighed three separate test samples at 0.17 gram 0.204 gram and 2.3 grams What is the total weight of the three samples?
2.674 grams
Which two samples of gas at STP contain the same total number of molecules?
Theoretically, if they have the same volume, all samples will contain the same number of molecules.
Can a robin have 7 eggs?
yes, even more during a certain period. Total eggs that incubate are usually much great than 7.
What can be found at the Total Beauty website?
The website for Total Beauty provides a great deal of information. The site offers beauty advice, beauty tips, samples of cosmetics and different hairstyles as well.

They core drill from the surface down and remove samples. These core samples give them the coal seam thickness and coal quality. Multiply the seam thickness by total area and you have the coal reserves, typically measured in acre-feet.
What is being measured when looking at the net change in displacement of the potato samples?
The net change in displacement of the potato samples is measuring the overall movement or shift in position of the potatoes. It indicates the total distance and direction that the potatoes have moved from their initial position to their final position.
What is the definition of number of samples in statistics?
The number of samples, or sample size, is the number of measurements performed for a particular statistic. For instance, if you were trying to calculate the average price for a bottle of Ardbeg 10 year old Scotch whisky, the number of samples would be the total number of prices you found for Ardbeg at various liquor stores. To continue on with this example, to get the average price, you would then add up all of the prices you measured and then divide that by the number of samples, as described above. It should be obvious that the more stores you visit to measure the price, in this case meaning the higher number of samples you obtain, the more accurate your value for the average price will be.
Is earthshaker a real ben 10 alien?
may be earthshaker is not been unlock by the omnitrix. because, total of omnitrix DNA is 1,000,910 samples.(including andromeda aliens)
