# Problems
**1. How many neutrons and protons are there in the nuclei of the following atoms:**

| Atom              | Protons | Neutrons |
| ----------------- | ------- | -------- |
| $^7\text{Li}$     | 3       | 4        |
| $^{24} \text{Mg}$ | 12      | 12       |
| $^{135}\text{Xe}$ | 54      | 81       |
| $^{209}\text{Bi}$ | 83      | 126      |
| $^{222}\text{Rn}$ | 86      | 136      |
**2. The atomic weight of $^{59}\text{Co}$ is 58.93319. How many times heavier is $^{12}\text{C}$? **
$\frac{ ^{59}\text{Co}}{^{12}\text{C}} = \frac{58.93319}{12.00000} = 4.91110 \text{ times larger}$

**3. How many atoms are there in 10g of $^{12}\text{C}$?**
