a. How many molecules strike a 1.00-cm 2 surface during 1 min if the surface is exposed

Question:

a. How many molecules strike a 1.00-cm² surface during 1 min if the surface is exposed to O₂ at 1.00 atm and 298 K?

b. Ultra-high-vacuum studies typically employ pressures on the order of 10^–10 Torr. How many collisions will occur at this pressure at 298 K?

For O₂, M = 0.0320 kg mol^–1 and Z_c = PN_A / (2πMRT) ^1/2
