1.60 g of a metal were dissolved in `HNO_3` to prepare its nitrate. The nitrate was strongly heated when 2.0 g of the metal oxide was obtained. Calculate the equivalent weight of the metal.

Explanation

To calculate the equivalent weight of the metal, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Mass of the metal (M) = 1.60 g
- Mass of the metal oxide (MO) = 2.00 g
- Molar mass of oxygen (O) = 16 g/mol
