Prepare the sample for 14C dating. In order to do this calculation, you first need to know that one Bq refers to decay of one nucleus in one second. Now you can calculate how long it will take for 12,360 decays to occur. The activity as given in the question statement is 1.10 Bq, all you have to do is to multiply the number of decays to the Bq value given.
1.10 × 12,360 = 13,600 seconds
Hope that answers the question, have a great day!
Answer:yes
