If that current persists for 1.62 min, how many conduction electrons pass through your heart? Number Units the absolute tolerance is +-1.OE+18 Question Attempts: 0 of 7 used SAVE FOR LATER SURMIT ANSWER version 4.24.7.7 MacBook Air esc Fr F3 F4 FS

Explanation / Answer

Charge passing = Current * time

q = I*t

= 0.3*1.62*60

= 29.16 C

so number of electrons = 29.16 / (1.6*10^-19)

= 1.8225*10^20 electrons
