Question

**Match the concentration terms with their properties:**

**Column I:**
(A) Molarity
(B) Molality
(C) Mole fraction
(D) Normality

**Column II:**
(P) Temperature dependent
(Q) Temperature independent
(R) Unitless
(S) Units: $mol \cdot kg^{-1}$

Prashant Kotian · Accepted Answer

Correct answer: (A) $\RIGHTARROW$ P
(B) $\RIGHTARROW$ Q, S
(C) $\RIGHTARROW$ Q, R
(D) $\RIGHTARROW$ P. **(A & D)** Molarity and Normality are volume-based. Since volume changes with temperature, they are temperature dependent (P).
**(B)** Molality is mass-based, so temperature independent (Q). Its unit is (S).
**(C)** Mole fraction is a ratio of moles, making it unitless (R) and temperature independent (Q).
