A gas jar contains 1.6 g of sulphur dioxide gas at S. T.P. calculate no. of moles [S = 32, O = 16]

Explanation

To calculate the number of moles of sulfur dioxide (SO₂) gas in a gas jar containing 1.6 g at standard temperature and pressure (STP), we will follow these steps:

### Step 1: Determine the molecular weight of sulfur dioxide (SO₂)
- The molecular weight of SO₂ is calculated using the atomic weights of sulfur (S) and oxygen (O).
- Given:
- Atomic weight of S = 32 g/mol
- Atomic weight of O = 16 g/mol
- SO₂ consists of 1 sulfur atom and 2 oxygen atoms.
