If 11,243 atoms of helium pass through a 3 square meter plate area every 1.2 hours, and if this flux is constant with time, compute the flux of helium in units of atoms per m2 per second. Answer Format: X.XX Unit: 1/(m2 s)

Answer :

Answer:

0.87 atom/m^2.s

Explanation:

Flux of helium = number of atoms of helium/area×time

Number of atoms of helium = 11,243

Area = 3 m^2

Time = 1.2 hours = 1.2×3600 = 4,320 s

Flux of helium = 11,243/3×4,320 = 11,243/12,960 = 0.87 atom/m^2.s
