Question

Calculate average velocity of nitrogen molecule at STP

Answer 1

Answer:

Using the formula and method that THE nerd used:

v = √(3RT/M)

M is the molar mass (in kg)

R is the universal gas constant

T is the temp, in Kelvin

Molar mass of N2 = 28 g = 0.028 kg

T = 273 K

v = √(3*8.314*273/0.028)

= 493 m/s
