A mass of a certain radioactive element decays at a rate of 18.5 billion disintegrations per minute.What is its activity in curies (Ci)?...in
becquerels (Bq)?

18.5 GBq which is about 0.5 Curie... Because a Bq equals an emmision per second and a curie equals 37 billion Bq.
Do your own homework in the future!

If I could do my own homework I wouldn't need this LOL!!! Does anyone have a more complete answer?

And don't crosspost!

What do you mean, more complete?
1 disintegration/second = 1Bq
G, giga, is a prefix for 1 billion. 18.5 billion = 18.5Gx
18.5GBq/37GBq=~.5Ci
