percentage error= experimental value-accepted value/ accepted value x 100
(percentage error is negative only if the accepted value is larger than the experimental value)
percentage error= 9.67-9.82/9.82 x 100
percentage error= -1.6
If the correct mass is 9.82g and the estimated mass is 9.67g, the percentage error is ~1.53% (1.52749490835%)
they must be correct and they must be the right kind of sample
An inductive generalization takes a sample of a population and makes a conclusion regarding the entirepopulation.Inductive Generalizations take the form..X percent of observed Fs are GsthereforeX percent of all Fs are GsFor example, an experiment may test the effects of a drug on lab mice. They might reason..80% of observed mice die when given the drug.therefore80% of all mice die when given the drug.The argument's strength depends on the sample. A sample that is not representative of the population is called a biased sample.
Again another of my homework questions and i think its control
The answer is Random Sample
Sensitivity in diagnostic laboratory testing represents the smallest amount of substance in a sample that can be accurately measured by an assay. Specificity in a diagnostic laboratory refers to the ability of an assay to measure one particular organism or substance.
Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.
random sample or probability sample
The goal of area normalization is to correct for sample size discrepances, that in a negative way affects the sum of all measured solutes. Example If 4 peaks are being measured and the sum total area of all peaks turns out to be less than or greater than 100 percent, Normalization corrects for this and shifts all peaks by the needed percentage to bring them to a sum of 100 percent. If the sum total equals 90 percent, then normalization will shift up each individual peak 10 percent, which will bring the sum up to 100 percent..
Mass
To determine the percentage of oxygen in FeCr2O4, you would first calculate the molar mass of the compound (iron(II) chromite) using the atomic masses of each element (Fe = 55.85 g/mol, Cr = 51.996 g/mol, O = 16 g/mol). Then, calculate the molar mass percentages of each element within the compound, and finally, determine the percentage of oxygen by mass in the compound.

The correct spelling is "sample".
Mass measures the amount of matter in a sample.
I measured a density of 1.0663 g with a sample size of 50.
That is the correct spelling of "sampling" (taking a sample).
The second one, "A sample of policies were tested."
place the sample on the microscope slide and observe it.
