You must show how to get answer for points

Phosphorus-32 is widely used in biochemical research, as a radioactive label. It has a half-life of 14.28 days. (A) Determine the rate constant lambda of 32P. Suppose you order a sample of adenosine triphosphate (ATP) labeled with 32P. The manufacturer states that at 12:00 noon on August 15, the activity of the sample was 3800 Bq. The sample is mailed and reaches you at 12:00 noon on August 18, 3.00 days later. Find the activity of the sample when you receive it. (Keep only 3 significant digits.)

Explanation / Answer

As we know that

Rate Constant = 0.693/Half Life

= 0.693/14.28

Rate Constant , lambda= 0.04854 days^-1

Herre Loss in Activity = Time*Rate Constant*Initial Activity

= (0.04854/days)*(3 days)*(3800 Bq)

= 553.35 Bq

Therefore After 3 days Activity = (3800 - 553.35)Bq

= 3246.7 Bq (approx)
