Atomic mass unit is determined by Oxygen-16?
One atomic mass unit (amu) is defined as one-twelfth of the mass of a carbon-12 atom. While oxygen-16 has a mass of 16 atomic mass units, it is not the basis for defining the amu, which is anchored to carbon-12.
Calculate the average atomic mass of an unknown element that has two naturally-occurring isotopes The first isotope occurs 75.47 percent of the time and has a mass of 248.7 amu The second isotope occu?
To calculate the average atomic mass, multiply the mass of each isotope by its natural abundance (expressed as a decimal), then add the results together. For the unknown element: Average atomic mass = (0.7547 * 248.7 amu) + (0.2453 * x) Given the only known isotope mass is 248.7 amu, you'll have to provide the mass of the second isotope to determine the average atomic mass.
What is the atomic mass of the unstable isotope sulphur 35?
34.98008 AMU
The naturally occurring isotopes of sulfur have masses of 32 33 34 and 36 amu. The atomic mass of sulfur is 32.06 amu. Which of these isotopes is the most abundant?
The isotope with a mass of 32 amu is the most abundant. This can be determined by comparing the atomic mass of sulfur (32.06 amu) to the masses of the isotopes. Since the atomic mass is closest to 32 amu, this isotope is the most abundant.
What element is the atomic base unit amu based off of?
The atomic mass unit (amu) is based on the carbon-12 isotope, with 1 amu defined as one twelfth of the mass of a carbon-12 atom. This definition allows for easier comparison of the masses of different atoms.
Chlorine has 2 isotopes and These have atomic masses 34.9689 amu and 36.9659 amu respectively Their ratio in nature is 75.77 percent and 24.23 percent respectively Calculate the average atomic ma?
Atomic mass of = 34.9689 amu Atomic mass of = 36.9659 amu % of = 75.77 % of = 24.23 Average atomic mass = amu Found this answer on examville.com
What does amu measure?
amu is an anime character in shugo chara ------------------------------------------------- The atomic mass unit (amu) is 1/12 from the atomic mass of the isotope 12C in his ground state.

What is the AMU of Seaborgium?
IUPAC credited seaborgium with the mass [269]; the atomic mass of this isotope is 269,128 63(39) amu.
The naturally occurring isotopes of sulfur have masses of 32 33 34 and 36 amu. The atomic mass of sulfur is 32.06 amu. Which of these isotopes is the most abundant?
The isotope with a mass of 32 amu is the most abundant. This can be determined by comparing the atomic mass of sulfur (32.06 amu) to the masses of the isotopes. Since the atomic mass is closest to 32 amu, this isotope is the most abundant.
What is the element with the least atomic mass is hydrogen or helium?
Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).
One has an atomic weight of 120.9038 amu with 57.25 percent abundance the other has an amu of 122.8831 what is the atomic weight of the element?
To calculate the atomic weight of the element, you need to consider the weighted average of the two isotopes based on their abundance. Atomic weight = (atomic mass isotope 1 * abundance isotope 1) + (atomic mass isotope 2 * abundance isotope 2) Plugging in the values: Atomic weight = (120.9038 amu * 0.5725) + (122.8831 amu * 0.4275) = 69.17 + 52.6 = 121.77 amu.
What element is the atomic base unit amu based off of?
The atomic mass unit (amu) is based on the carbon-12 isotope, with 1 amu defined as one twelfth of the mass of a carbon-12 atom. This definition allows for easier comparison of the masses of different atoms.
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?
