WebN(14C) = (5.02 × 1025)(1.3 × 10−12) = 6.52 × 1013. Now we can find the activity A by using the equation A = 0.693N t1/2. Entering known values gives us A = 0.693(6.52 × 1013) 5730y = 7.89 × 109y−1 or 7.89 × 109 decays per year. To convert this to the unit Bq, we simply convert years to seconds. Thus, A = (7.89 × 109y−1) 1.00y 3.16 × 107s = 250Bq, WebApr 30, 2015 · In contrast, the average copy number was only 9.03 × 10 5 in the remaining eight MRSA samples identified as non-pathogenic colonizers. The average copy number was 1.75 × 10 5 from 13 MRSA positive cases detected using the quantitative PCR assay. These results reveal a statistical difference in the DNA copy number between the …
