Which of the following solutions have the same concentration?
(i) 20 g of NaOH in 200 mL of solution
(ii) 0.5 mole of KCl in 200 mL of solution
(iii) 40 g of NaOH in 100 mL of solution
(iv) 20 g Of KOH in 200 mL of solution
The answers are options (i) and (ii)
Explanation: (i) 20 g NaOH in 200 mL solution.
mol of NaOH
(ii) Molar concentration Of NaOH
as 200 mL = 0.2 L
Molar concentration of KCl =
