Questions and Answers

What is the formula for calculating molarity?

Molarity = No. of moles of solute + No. of liters of solution

Molarity = No. of liters of solution / No. of moles of solute

Molarity = No. of liters of solution - No. of moles of solute

Molarity = No. of moles of solute / No. of liters of solution (correct)

When the molarity is expressed as 0.5 M NaOH, what does this indicate about the solution?

There are 0.5 moles of NaOH in 1 liter of solution (correct)

There are 1 mole of NaOH in 2 liters of solution

There are 0.5 liters of NaOH in 1 mole of solution

There are 0.5 moles of NaOH in 0.5 liters of solution

Which unit is commonly used to express molarity?

mass/L

mol/100mL

mol/L (correct)

volume/moles

Study Notes

Molarity

The most commonly used unit in chemistry.
Molarity = Number of moles of solute / Number of liters of solution
Unit: (mol/L) or (mol.L-1) or M
Example: 0.5 M NaOH means 0.5 mole NaOH / 1L solution

Molarity Calculations

To calculate molarity, we need to know the number of moles of solute and the number of liters of solution
Adding water makes the solution less concentrated
This inverse relationship can be expressed with the following equation: Mi × Vi = Mf × Vf
Increasing the final volume (Vf) decreases the final molarity (Mf)
