Multiple Choice
Which of the following represents the correct units for molarity?
A
mol/kg
B
g/L
C
L/mol
D
mol/L
Verified step by step guidance1
Understand that molarity is a measure of concentration defined as the number of moles of solute dissolved in one liter of solution.
Recall the formula for molarity: \(M = \frac{\text{moles of solute}}{\text{liters of solution}}\).
Analyze each unit option: mol/kg represents molality, g/L is a mass concentration, and L/mol is the inverse of molarity.
Identify that the correct unit for molarity must have moles in the numerator and liters in the denominator, matching \(\text{mol}/\text{L}\).
Conclude that the correct units for molarity are \(\text{mol}/\text{L}\), which directly corresponds to the definition of molarity.
