12 amu
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.
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.

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.
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.
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
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.
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.
Boron is the element that has two isotopes with atomic masses of approximately 10 amu and 11 amu. The most common isotope of Boron is Boron-11, which has an atomic mass of 11 amu, while the less common isotope Boron-10 has an atomic mass of 10 amu.
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.

IUPAC credited seaborgium with the mass [269]; the atomic mass of this isotope is 269,128 63(39) amu.
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.
Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).
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.
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.
