1.49g of ammonia at STP occupies a volume of 3.48 `dm^3` calculate the molar mass of ammonia.

Options

A. 11.48g/mol
B. 9.6g/mol
C. 22.4g/mol
D. None of these

Explanation

To calculate the molar mass of ammonia (NH₃) from the given data, we can follow these steps:

### Step 1: Understand the given data
We have:
- Mass of ammonia (NH₃) = 1.49 g
- Volume at STP = 3.48 dm³

### Step 2: Convert volume from dm³ to liters
