The term " atomic mass " refers to the mass of a single atom. The mass of a single atom of carbon-12 is defined as exactly 12 u. The term atomic mass is also often used (though technically, incorrectly) to refer to the average atomic mass of all of the isotopes of an element.Home theater receiver repair near me
The two most abundant isotopes of carbon are carbon-12 (mass = 12.00 amu) and carbon-13 (mass = 13.00 amu). Their relative abundances are 98.9% and 1.10%, respectively. Calculate the average atomic mass of carbon.

To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance (expressed as a decimal). Then, add the results together and round off to an appropriate number of significant figures. This is the solution for carbon: (12.000000) (0.9890) + (13.003355) (0.0110) = 12.011 amu.

Jun 12, 2012 · The unified atomic mass unit (Also known as amu, symbol: u) or dalton (symbol: Da) is a unit that is used for indicating mass on an atomic or molecular scale. It is defined as one twelfth of the rest mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 1.660538921*10^−27 kg.

### Ace hardware drywall mud

Draw the carbon-12 nucleus and calculate the mass of one atom in amu and g. A correctly drawn model of the nucleus will have six protons and six neutrons packed in a tight spherical shape. Because neutrons and protons have about the same mass, treat the six neutrons and six protons in the C-12 atom as 12 protons. 1.672 24 10 g __ 1 proton 12 ...

We found the mass defect of He to be 0.0303769 amu. To obtain the binding energy in units of joules, we must convert the mass defect from atomic mass units to kilograms. Multiplying the mass defect in kilograms by the square of the speed of light in units of meters per second gives a binding energy for a single helium atom of 4.53358 x 10 -12 ...
