Step 1
The atomic mass unit is defined such that one amu is exactly 1/12th the mass of one carbon-12 atom. The atomic mass of an element in amu is roughly equal to the sum of the number of protons and neutrons in the atom. For grams, it's a measure of mass in the metric Show more…

The accepted atomic mass of nitrogen is $14.0067 \mathrm{u}$. Approximately $99.632 \%$ of natural nitrogen is ${ }^{14} \mathrm{~N}$, which has an isotopic mass of $14.0031 \mathrm{u}$. The remaining nitrogen is ${ }^{15} \mathrm{~N}$. What is the isotopic mass of ${ }^{15} \mathrm{~N}$ in atomic mass units?
Determine the mass (in grams) of nitrogen that contains 31 atoms N.
