Molarity is a measure of the concentration of a solute in a solution, or of any chemical species in terms of amount of substance in a given volume.
Think about making lemonade. If you add one scoop of lemonade powder to one cup of water, that's like having a 1 molar (M) solution. If you add two scoops to the same amount of water, it becomes more concentrated - now it's a 2M solution. The more scoops (solute) you add per cup (volume), the higher the molarity.
Molality: This is another way to express concentration, but instead of volume, it uses mass. It's defined as moles of solute per kilogram of solvent.
Normality: This measures concentration in terms equivalent weight per liter. It’s often used when discussing acid-base reactions.
Solute: This is what gets dissolved into something else. In our lemonade example, the powder would be the solute.
What is the molarity of 100mL HCl if it completely reacts with 50 mL of 2.0 M LiOH in order to completely neutralize the solution?
Why is the common ion replaced with the molarity already present (ex. 3M of a salt) instead of 3 +/- nx (n represents the ratio multiplier)?
Which of the following statements about molarity at the equivalence point is true?
What is the molarity of a solution that contains 5.00 g of NaCl in 250.0 mL of solution?
A solution contains 0.500 moles of glucose (C6H12O6) in 500.0 mL of solution. What is the molarity of the solution?
