Weighted average mass of the mixture of its isotopes?
Average atomic mass I think.
What is the weighted average atomic mass of bromine?
79.9173125
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
Why is the atomic mass of sulfur listed on the periodic table not a whole number?
The atomic mass given on the periodic table is a weighted average of all the isotopes, weighted by abundance of each isotope
Weighted average atomic mass?
What is weighted average atomic number
Is fifo the inventory costing method that follows the physical flow of the goods?
no, FIFO, LIFO, and weighted-average method are cost flow assumptions these assumptions bear no relation to the physical flow of goods; they are merely used to assign costs to inventory units.
Is The Dow Jones Industrial Average a market value weighted or price weighted index?
The Dow Jones Industrial average is a price weighted index.
What do you add to your unweighted average?
You can't convert an unweighted average into a weighted average simply by adding something. You have to do the whole calculation for the weighted average.
What is the difference between Average method vs weighted average method?
in weighted average method we assigns the weight to the averages while in average methods we dnt do this
What is the difference between average and weighted average?
weighted average is an average in which each quantity to be averaged is assigned a weight. These weightings determine the relative importance of each quantity on the average.
Why are multiples used in weighted average calculation?
The multiples are the weights (or importance) associated with each observation on which the weighted average is based.
Weighted mean sample problem?
weighted mean is getting the weighted average of students. normally, it is always use in computing the general average of the students to determine the ranking of the whole class.
What is the abbreviation for weighted average?
WAVG
Is weighted average inventory valuation GAAP?
Yes, along with FIFO and LIFO, Weighted average is a generally accepted accounting principle.
Difference between simple and weighted average?
In a simple average every value is worth the same, but in a weighted average, the frequency of each value is taken into consideration.
What is a flow weighted average?
A flow weighted average is found by dividing the total load over the estimation time by the total stream flow.
