What is the answer to this chemistry problem? 🤔?
The charge of an electron is -1.602 x 10-19 C. For the photoelectric effect, how many microamperes (1 A = 1 C/s) of electrical current are produced when a metal is bombarded by 8.50x1013 photons each second? Assume that each photon has sufficient energy to eject one electron. (Note currents are reported as positive values.)

your numbers are meaningless, please use proper terminology.
(8.50 × 10^13 photons/second) × (1 electron / 1 photon) ×
(1.602 × 10^-19 C/electron) = 1.3617 × 10^-5 C/second = 13.6 μA
