**Question 24: Calculate the Mass in Grams**

Determine the mass in grams of each of the following:

- **d.** \(4.86 \times 10^{24}\) atoms Au
- **e.** 6.50 mol Cu
- **f.** \(2.57 \times 10^8\) mol S
- **g.** \(1.05 \times 10^{18}\) atoms Hg

**Explanation for Students:**

To find the mass in grams, you will need to use Avogadro's number (\(6.022 \times 10^{23}\) atoms/mol) and the molar mass of each element from the periodic table. Use these conversions:

1. **For atoms to grams:**
   - Convert atoms to moles using Avogadro's number.
   - Multiply the number of moles by the molar mass of the element.

2. **For moles to grams:**
   - Multiply the number of moles directly by the molar mass of the element.
