Calculate the volume occupied by (i) 28 u nitrogen gas (ii) 28 g `N_(2)` gas at STP.

Explanation

To solve the problem, we need to calculate the volume occupied by two different amounts of nitrogen gas: (i) 28 u (atomic mass units) and (ii) 28 g of \( N_2 \) gas at STP (Standard Temperature and Pressure).

### Step-by-Step Solution:

**Step 1: Understanding Atomic Mass Unit (amu)**
- 1 amu (atomic mass unit) is defined as \( 1.66 \times 10^{-24} \) grams.
- Therefore, 28 u of nitrogen can be converted to grams as follows:
\[
