Compute the mass in grams for each of the following:
3.0 mol of `NH_(3)`

Explanation

To compute the mass in grams for 3.0 moles of ammonia (NH₃), we can follow these steps:

### Step 1: Identify the number of moles
We are given that the number of moles of ammonia (NH₃) is 3.0 moles.

### Step 2: Calculate the molar mass of ammonia (NH₃)
The molar mass of ammonia can be calculated by adding the molar masses of its constituent elements:
- Molar mass of nitrogen (N) = 14 g/mol
