# If the root-mean-square velocity of nitrogen molecules is 500m / s and its density is 1.35kg / m “3, then the nitrogen pressure is?

| Initial data: Vkv (mean square velocity of nitrogen molecules) = 500 m / s; ρ (nitrogen density) = 1.35 kg / m3.

The nitrogen pressure at the given parameters can be calculated by the formula: P = 1/3 * ρ * Vav ^ 2.

Let’s perform the calculation: P = 1/3 * 1.35 * 500 ^ 2 = 112500 Pa.

Answer: The nitrogen pressure at the given parameters is 112500 Pa.
