JEE Main 25 July 2022, Shift 2, Chemistry Q64

Question 64 of 90 in this shift, Chemistry question 4 of 30, Section A.

The molar conductivity of a conductivity cell filled with 10 moles of 20 mL NaCl solution is Λm1\Lambda_{m1} and that of 20 moles another identical cell heaving 80 mL NaCl solution is Λm2\Lambda_{m2} , The conductivities exhibited by these two cells are same. The relationship between Λm2\Lambda_{m2} and Λm1\Lambda_{m1} is
  1. (1)Λm2=2Λm1\Lambda_{m2} = 2\Lambda_{m1}Official answer
  2. (2)Λm2=Λm1/2\Lambda_{m2} = \Lambda_{m1} / 2
  3. (3)Λm2=Λm1\Lambda_{m2} = \Lambda_{m1}
  4. (4)Λm2=4Λm1\Lambda_{m2} = 4\Lambda_{m1}
