Determine the equivaleng weight of underlined element in the following compounds `:`
`underset( -)(S) O_(3)`

Explanation

To determine the equivalent weight of sulfur (S) in sulfur trioxide (SO₃), we can follow these steps:

### Step 1: Understand the concept of equivalent weight
Equivalent weight is defined as the molecular weight of an element or compound divided by its n-factor. The n-factor represents the number of moles of reactive species produced or consumed in a reaction.

### Step 2: Find the molecular weight of sulfur (S)
The atomic weight of sulfur (S) is approximately 32 g/mol.
