The density of an ideal gas is `1.25xx10^(-3)g cm^(-3)` at STP. Calculate the molecular weight of the gas.

Explanation

To calculate the molecular weight of the ideal gas given its density at STP, we can follow these steps:

### Step 1: Understand the Given Data
- Density of the gas, \( \rho = 1.25 \times 10^{-3} \, \text{g/cm}^3 \)
- Standard Temperature (STP), \( T = 273 \, \text{K} \)
- Standard Pressure (STP), \( P = 1 \times 10^5 \, \text{Pa} \)

### Step 2: Convert Density to kg/m³
