How can you find atomic number without the periodic table? How to calculate atomic mass of isotopes How to calculate the relative atomic mass of an element? How is the atomic mass of an element calculated? How can you calculate the number of neutrons (n) in an atom?
The sample you were given to analyze contained more carbon-13 than average. You know this because your relative atomic mass is higher than theperiodic table value, even though the periodic table number includes heavier isotopes, such as carbon-14. Also, note the numbers given on the periodic ...

The average mass of a carbon atom is 12.011. Assuming you could pick up one carbon atom, what is the chance that you would randomly get one with a mass of 12.011? Why? a. 0% b. 0.011% c. about 12% d. 12.011% e. greater than 50% f. none of th...
Knowing the relative fraction of each isotope of a particular element that occurs in nature allows you to calculate the atomic mass of that element, which, because it is an average, is not the mass of any one atom but a number that is between the heaviest and lightest isotopes pres...
