What is the number of electrons passed through an electrolyte solution when 1 ampere current is passed for 16.1 minutes?

Options

  1. A5.022 10²⁴
  2. B3.011 10²²
  3. C6.022 10²¹
  4. D2.022 10²³

Correct answer

C. 6.022 10²¹

Step-by-step solution

aligned & q = ne & q = I . t & n = no. of electrons & e = change of one electron & I = Current supplied & t = time in seconds & q =1 16.1 60= ne & n = 16.1 60 1.602 10⁻¹⁹ =6.022 10²¹ aligned
