JEE Previous Year Question
The density of a monobasic strong acid (Molar mass 24.2 g mol) is 1.21 kg L. The volume of its solution required for the complete neutralization of 25 mL of 0.24 M NaOH is_____________x mL (Nearest integer)
Topic: JEE PYQ
Answer: 12. Full step-by-step solution below.
Correct answer: 12
Solution
(12)millimole of NaOH = 0.24 x 25
millimole of acid = 0.24x25
mass of acid = 0.24 x 25 x 24.2 mg
for pure acid,
V = ;(d = 1.21kg/L =1.21 g/ml)
