Question

Largest number of ions is present in the electrolyte

• A. 50 g K₂SO₄(mol. wt. 174)
• B. 50 g NaCl (mol. wt. 58.5)
• C. 50 gNH₄CL (mol. wt. 53.5)
• D. 50 gCaCL₂ (mol. wt. 111)

Answer 1

The correct option is C

50 gNH₄CL (mol. wt. 53.5)

$no.ofions=\frac{W_t}{M.W_t}\times no.ofions\times N$
Since option C has the lowest molecular mass, it will have the most number of atoms. Remember, we are taking the same mass of all substances!
