Calculate r.m.s speed of `N_2` at 298 K in metre/s .

Options

A. 515.2
B. 51.52
C. 103.4
D. 170.6

Explanation

To calculate the root mean square (r.m.s) speed of nitrogen gas (N₂) at a temperature of 298 K, we can follow these steps:

### Step 1: Identify the formula for r.m.s speed
The formula for the r.m.s speed (Vrms) of a gas is given by:
\[ V_{rms} = \sqrt{\frac{3RT}{M}} \]
where:
...
