NEETChemistrySome Basic Concepts of ChemistryMCQ+4 / −1
2.5 litre of 1 M NaOH solution is mixed with another 3 litre of 0.5 M NaOH solution. Then find out molarity of resultant solution.
  1. A
    0.80 M
  2. B
    1.0 M
  3. C
    0.73 M
  4. D
    0.50 M

Correct answer: C

From molarity equation

M1V1 + M2V2 = MV

⇒\Rightarrow⇒ 1× 2.5 + 0.5 × 3 = M × 5.5

⇒\Rightarrow⇒ M = 45.5{4 \over {5.5}}5.54​ = 0.73M
