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.
