    C ratio as the ratio in the atmosphere, and since the size of the sample is known, the total number of atoms in the sample can be calculated, yielding N 0, the number of 14 C atoms in the original sample. Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation ...
