Type: MCQ-conceptual-Medium-Class 12
Concentration terms like mass percentage, ppm, mole fraction and molality do not depend on temperature. However, molarity is a function of temperature because
A
volume depends on temperature and molarity involves volume
B
molarity involves non-volatile solute while all other terms involve volatile solute
C
number of moles of solute change with change in temperature
D
molarity is used for polar solvents only
Correct Answer
