What is the activity of a 217 uCi sample of carbon14 in becq

What is the activity of a 21.7 uCi sample of carbon-14 in becquerels? Number Bq

1 Ci = 3.7 x10^10 disintegrations/s

1 Bq= 1 disintegration/s

21.7 uCi = 21.7 x 10^-6 Ci

= 21.7 x 10^-6 x 3.7 x10^10

= 802900 disintegrations / s

activity = 8.03 x 10^5 Bq
