**Metric Prefixes and Calculation of Molarity**

**Metric Prefixes:**

- **centi (c):** \(10^2\) or 100
- **milli (m):** \(10^3\) or 1,000
- **micro (µ):** \(10^6\) or 1,000,000
- **nano (n):** \(10^9\) or 1,000,000,000

**Problem:**

Calculate the molarity of a solution of 579.6 g ZnSO₄ (molar mass 161.47 g/mol) in \(6.5 \times 10^4\) mL of solution.

**Options:**

- A. \(8.9 \times 10^{-3}\) M
- B. 2.5 M
- C. none of these
- D. \(2.5 \times 10^{-3}\) M
- E. \(5.5 \times 10^{-2}\) M
- F. 18 M
- G. 8.9 M
- H. \(5.5 \times 10^{-5}\) M

---

To solve this problem, start by converting the mass of ZnSO₄ into moles using the molar mass, and then calculate the molarity by dividing the moles by the volume of the solution in liters.
