What is the activity of a 18.9 μCi sample of carbon-14 in becquerels?

There are 3.7E10 dps/Ci

1 Bq = 1 dps.
So 18.9 uCi will be
18.9E-6 Ci.
(3.7E10 dps/1 Ci) x 18.9E-6 Ci = ? dps
Since 1 Bq = 1 dps, then ? dps = ? Bq
Check out my thinking.

To find the activity of a sample in becquerels, you need to convert the given value from microcurie (μCi) to becquerels (Bq).

Now, the conversion factor between microcurie and becquerel is:

1 μCi = 37,000 Bq

So, to convert the given value of 18.9 μCi to becquerels, you can use the following calculation:

Activity (in Bq) = 18.9 μCi * 37,000 Bq/μCi

Now, let's calculate the activity:

Activity = 18.9 μCi * 37,000 Bq/μCi
= 699,300 Bq

Therefore, the activity of a 18.9 μCi sample of carbon-14 is 699,300 becquerels.

To convert from microcurie (μCi) to becquerel (Bq), you can use the following conversion factor:

1 μCi = 37,000 Bq

Therefore, to convert the activity of a 18.9 μCi sample of carbon-14 to becquerels, you can multiply it by the conversion factor:

18.9 μCi * 37,000 Bq/μCi = 699,300 Bq

So, the activity of a 18.9 μCi sample of carbon-14 is approximately 699,300 becquerels.
