The Activity of a Radioactive Sample Is the Number of Decay

The activity of a radioactive sample is the number of decay events per second.The SI unit of activity is the becquerel.An older unit for activity is the curie.What is the activity in Bq of a sample with an activity of 47 µCi of radiation? (1 Bq = 1 decay/s and 1 Ci = 3.7 * 10¹⁰ Bq)

A) 7.9 * 10² Bq
B) 7.9 *10⁸ Bq
C) 1.7 * 10¹² Bq
D) 1.7 *10⁶ Bq
E) 1.3 *10^-16 Bq
