Example:
- 454 g of orange jam contain 83 g sugar
454 g jam---------------83 g sugar
100 g jam----------------x g sugar
x= 100x83/454= 18,18 g sugar (or 18 % sugar)

Why is each isotope's mass multiplied by the isotope's percent abundance?
That is done to calculate the weighted average.
Is mass percent the same as percent by mass?
They are synonyms.
How do you calculate the atomic mass of an element with different isotopes?
To calculate average atomic mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful : atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)
How is the atomic mass of each element on the periodic table calculate?
The atomic mass listed on most periodic tables is actually the average atomic mass representing the average atomic masses of the various isotopes of an element depending on their percent natural abundance. Refer to the answers.com question: What is the formula for finding average atomic mass? for a detailed explanation on how to calculate this value.

Calculate the percent of water of FeSO47H20?
1. Find the molar mass (MM) of the substances.MM FeSO4 = 151.91g+MM 7H2O = 126.11gMM FeSO4 x 7H2O = 278.02g2. Find the percent water of hydrate.Divide the mass of water by the mass of the hydrate; multiply result by 100%.126.11g278.02g x 100%Percent water of FeSO4 * 7H2O is 45.36%.Finding Molar Mass# atoms Element A x atomic mass Element A = Mass A# atoms Element B x atomic mass Element B = Mass B... etc.Add up all the mass values for the substance and you have the molar mass of the substance.
What is the equation used to calculate percent by mass?
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
How do you calculate the percent chloride with the volhard method?
(mass /volume)x100
The 1st isotope occurs 75.47 percent of the time and has a mass of 248.7 amu the 2nd isotope occurs 24.53 percent of the time and has a mass of 249.4 amu calculate the average atomic mass?
248.90
Why is each isotope's mass multiplied by the isotope's percent abundance?
That is done to calculate the weighted average.
Calculate the mole fraction of benzene in solution containing 30 percent by mass in carbon tetrachloride?
calculate the mole fraction of benzene in solution containing 30% by mass in carbon tetra chlorid
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
Calculate the molarity of a hydrochloric acid solution that is 18.25 percent HCl by mass and has a density 1.2gmL?
6M
Is mass percent the same as percent by mass?
They are synonyms.
Calculate the percent nitrogen by mass in chlorophyll C55H72MgN4O5?
You would first calculate the atomic mass of chlorophyll, which would be 892.9 g/mol (I did not calculate this out, but looked it up b/c of the complexity of the calculation). Then find the molar mass of the Nitrogen part of the chlorophyll (4 mol *14.01 g/mol=56.04 grams). Then, take 56.04 grams/892.9grams= .06276, or 6.276% nitrogen by mass
Bernard's star has a mass of how many times the mass of sun?
15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
The number of atoms of one element in the compound
How do you calculate the grams of an element in a specific amount of a compound?
Multiply the mass of the compound by the conversion factor based on the percent composition of the element in the compound
