Question

Calculate the rms speed of a nitrogen molecule at a room temperature?

Step-by-Step Solution

Verified

Answer

The rms speed of a nitrogen molecule at room temperature is 16.34 m/s

1Step 2 : Arriving at rms speed by substituting the data ,

Since we are recalculating for Nitrogen molecule the molar mass of N₂₌28

Substituting all the values ,

$V_{r m s} = \sqrt{\frac{3 \times 8.314 \times 300}{28}}$

V_rms=16.34m/s
