The data is as follows:
1. the delta value for the 13-C (carbon 13) = -7.2
2. 14-C (carbon 14) activity = 8.16 dpm/g
I need help calculating the age of this carbon, and if possible, corrected for isotopic fractionation.© BrainMass Inc. brainmass.com October 24, 2018, 6:24 pm ad1c9bdddf
So, first we need to calculate the fraction of 13-C in the sample. Since 13-C is stable, this will give us an indication of how much fractionation happens in this particular sample we are dealing with.
Using the percentages: 12-C (98.89%) and 13-C (1.11%)
We have the ratio (R_std) = 1.11/98.89 = 0.01122
Now the ...
This solution is provided in 262 words. It calculates the fractionation, as well as uses this information and half-life calculation to carbon date the sample.
