Homework Statement
A 1.3m×1.3m×1.3m cube of nitrogen gas is at 20∘C and 1.5 atm. Estimate the number of molecules in the cube with a speed between 700 m/s and 1000 m/s.
Homework Equations
P= (1/3) (N/V) (Mv2rms)
The Attempt at a Solution
20oc = 293 K
1.5 atm = 151950 Pa
Solving for N
N= 3PV/(mv2rms)
N= 3(151950)(2.197) / (28 x 12202)
N= 0.024 Molecules ?
