Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
A molar solution (1 M) has 1 mol of solute per litre. Solutions of lower molarity are named with the same SI prefixes used for units: deci = 10−1, centi = 10−2, milli = 10−3, micro = 10−6.
(A) \(10^{-6}\) M solution — This matches (II) Micromolar solution. Micro means 10−6.
(B) 0.1 M solution — This matches (I) Decimolar solution. 0.1 = 10−1, deci.
(C) 0.001 M solution — This matches (III) Millimolar solution. 0.001 = 10−3, milli.
(D) 0.01 M solution — This matches (IV) Centimolar solution. 0.01 = 10−2, centi.
Shortcut: (A)-(II) appears only in Option (1).
