What mass of `C^(14)` with `t_(1//2) = 5730` years has activity equal to curie?

Explanation

To find the mass of Carbon-14 (C-14) that has an activity equal to 1 Curie, we can follow these steps:

### Step 1: Understand the relationship between activity and half-life
1. **Activity (A)** is defined as the number of disintegrations per second. 1 Curie (Ci) is equal to \(3.7 \times 10^{10}\) disintegrations per second.

### Step 2: Convert half-life from years to seconds
2. The half-life of C-14 is given as 5730 years. We need to convert this into seconds:
