We're asked to determine which mass is closest to the atomic mass of carbon without doing any calculations.
We know that carbon has two naturally occurring isotopes:
To do so, we will compare the mass of each isotope to the atomic mass of Carbon
Carbon has two naturally occurring isotopes: C-12 (natural abundance is 98.93%; mass is 12.0000 amu) and C-13 (natural abundance is 1.07%; mass is 13.0034 amu).
Without doing any calculations, determine which mass is closest to the atomic mass of carbon.
