Carbon exists in nature as three isotopes. given the atomic masses and relative abundance of the isotopes, what is the average atomic mass of carbon? isotope relative abundance atomic mass (amu) c-12 98.93 percent 12.000 c-13 1.07 percent 13.003 c-14 0.0000000001 percent 14.003 a. 12.000 amu b. 12.011 amu c. 13.002 amu d. 13.003 amu e. 14.003 amu

Respuesta :

The average atomic mass of carbon is 12.09 amu.

What is an atomic mass?

The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)

What is atomic mass formula?

Atomic mass = Mass of protons + Mass of neutrons + Mass of electrons.

How do you calculate atoms?

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
