Final answer:
Without additional information on the sample of 238Pu, such as its weight and half-life, we cannot calculate its original activity in becquerel(Bq), hence we cannot determine the correct option from the provided choices.
Step-by-step explanation:
The original activity of 238Pu in becquerel (Bq) is not explicitly provided in the information. To determine this value, we would need additional information, such as the weight of the sample and the half-life of the substance.
Knowing that 1 becquerel is defined as 1 decay per second, we can infer that activity directly depends on the amount of the radioactive substance and its half-life.
However, without more specific data regarding the particular sample of 238Pu, we cannot calculate its original activity.
Therefore, based on the provided information, it is not possible to select the correct answer from the options a. (1.01 × 10¹⁰ {Bq}), b. (2.02 × 10¹⁰ {Bq}), c. (3.03 × 10¹⁰ {Bq}), or d. (4.04 × 10¹⁰ {Bq}).
