Question

Match List I with List II

LIST I	LIST II
A. Molarity	I. mol
B. Mole Fraction	II. unitless
C. Mole	III. mol L-1
D. Molality	IV. mol kg-1

Choose the correct answer from the options given below:

• A. (A)- (I), (B)- (II), (C)- (IV), (D)- (III)
• B. (A)- (III), (B)- (II), (C)- (I), (D)- (IV)
• C. (A)- (II), (B)- (I), (C)- (III), (D)- (IV)
• D. (A)- (II), (B)- (III), (C)- (I), (D)- (IV)

Hint:

Remember that molarity is for solutions in liters, while molality uses mass of the solvent in kg.

Answer 1

The Correct Option is B

Molarity (\( M \)) is expressed as mol L\(^{-1}\). Mole Fraction is a ratio and thus unitless. Mole is counted in terms of moles. Molality (\( m \)) is expressed as mol kg\(^{-1}\).
