1.40 g of a metal when heated in a current of oxygen gave 1.93 g of the metal oxide. Calculate the equivalent weight of the metal.

Explanation

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

### Step 1: Determine the mass of oxygen that combined with the metal
We know the mass of the metal and the mass of the metal oxide formed. The mass of oxygen can be calculated as follows:

\[ \text{Mass of oxygen} = \text{Mass of metal oxide} - \text{Mass of metal} \]
